e1639b5345 device: Extend device_set_power_state API to support async requests
The existing device_set_power_state() API works only in synchronous
mode and this is not desirable for devices(ex: Gyro) which take
longer time (few 100 mSec) to suspend/resume.

To support async mode, a new callback argument is added to the API.
The device drivers can asynchronously suspend/resume and call the
callback function upon completion of the async request.

This commit adds the missing callback parameter to all the drivers
to make it compliant with the new API.

4344e27c26 all: Update reserved function names
Update reserved function names starting with one underscore, replacing
them as follows:
   '_k_' with 'z_'
   '_K_' with 'Z_'
   '_handler_' with 'z_handl_'
   '_Cstart' with 'z_cstart'
   '_Swap' with 'z_swap'

This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.

Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.

Various generator scripts have also been updated as well as perf,
linker and usb files. These are
   drivers/serial/uart_handlers.c
   include/linker/kobject-text.ld
   kernel/include/syscall_handler.h
   scripts/gen_kobject_list.py
   scripts/gen_syscall_header.py

e65f8ba1f2 kconfig: gpio: Remove lots of redundant GPIO dependencies
Most of these are from source'ing a file within an 'if GPIO', and then
adding another 'depends on GPIO' within it.

'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. There are no "conditional includes" in Kconfig, so
'if FOO' has no special meaning around a 'source'. Conditional includes
wouldn't be possible, because an 'if' condition could include (directly
or indirectly) forward references to symbols not defined yet.

Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.

e5ee8035c7 drivers: gpio: Fix mcux driver to init successfully with no irq
Some mcux gpio instances do not have dedicated interrupt vectors and
therefore conditionalize out the IRQ_CONNECT() and irq_enable() calls
during driver initialization. The driver initialization incorrectly
returned an error in this case, when really it just has nothing to do.
The driver can still be used without interrupts, and the gpio configure
function returns an error if an application tries otherwise.

Commit a68120de6d introduced a check on
the init return value to prevent applications from using drivers that
fail to initialize. This in turn caused zephyr/samples/basic/threads to
assert on the frdm_kl25z board. Fix this by modifying the mcux gpio
driver to return success when there is no interrupt to connect.

d75495709d drivers: gpio: fix mis-use of slist API in callback processing
The iterator over registered callbacks failed to account for the
possibility that the callback would remove itself from the list.  If
this occurred any remaining callbacks would no longer be reachable from
the node.  Switch to the slist iterator that is safe for self-removal.

Note that the slist API remains unsafe for removal of subsequent nodes.
Even with the corrected code removal of the next callback registration
(cached in tmp) will result in it being called anyway, with the
remaining unremoved registrations not being called.  If the next
callback were removed and re-registered on a different device, the
callbacks would be invoked for the wrong device.

Resolve this by a documentation change describing the conditions under
which a change to callback registration from within a callback are
permitted.  Add a similar note regarding the effect of adding a
callback.  The current event invocation behavior for callbacks added
within an event is explicitly left unspecified, though in the current
slist implementation newly added callbacks will not be invoked until the
next event.

3134468801 drivers: gpio: nrfx: fix lost level interrupts
Nordic devices detect edge interrupts through the PORT event which is
generated on a rising edge of DETECT, which itself is asserted when any
GPIO is configured for sense level detection and the GPIO's input signal
matches the configuration.

The previous code in Zephyr attempts to detect when at least one GPIO
SENSE signal is still asserted, and intentionally leaves the PORT event
uncleared to ensure the interrupt is re-entered.

This approach fails when no pin satisfies its SENSE condition during the
check but at least one input changes level between the completion of the
check and the clear of the PORT event.  Such a failure can be observed
on the pca20020 hardware when multiple sensors configured for level
triggers are active.  In this situation the corresponding sensor trigger
signals remain asserted but the PORT event required to drive their
processing has already been cleared.

The fix is to ensure that the SENSE configuration for all GPIOs across
all port instances is disabled prior to unconditionally clearing the
PORT event, then re-enabling the SENSE configuration for all GPIOs once
callbacks associated with detected SENSE triggers have been performed.
The act of re-enabling will ensure any relevant SENSE condition causes a
new rising edge on DETECT and so a new PORT event.

Closes issue #11806

20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig
These changes were obtained by running a script  created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:

1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
   #define X Y)
3. Check if that name is also the name of a Kconfig option
   3.a If it is, then do nothing
   3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
       has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
   (.c, .h, .ld)

Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.

Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c
