Convert tests to DEVICE_{DT_}DEFINE instead of DEVICE_AND_API_INIT
so we can deprecate DEVICE_AND_API_INIT in the future.

- Remove SYS_ prefix
- shorten POWER_MANAGEMENT to just PM
- DEVICE_POWER_MANAGEMENT -> PM_DEVICE
and use PM_ as the prefix for all PM related Kconfigs

Now that device_api attribute is unmodified at runtime, as well as all

A coccinelle rule is used for this:

There is nothing wrong with instance numbers and they are
recommended for use whenever possible, but this is an API
design problem because it's not always possible to get nodes
by instance number; in some cases, drivers need to get node
identifiers from node labels, for example.
Change these APIs (which are not yet in any Zephyr release)
to take node IDs instead of instance IDs.

Exercise the public macros as well as device_map().
This test has a whitelist for whatever reason; add
mps2_an385 so that the !DEVICE_MMIO_IS_IN_RAM stuff
is tested.

Device objects in Zephyr are currently placed into an array by linker
scripts, making it easy to iterate over all devices if the array
address and size can be obtained. This has applications in device
power management, but the existing API for this was available only
when that feature was enabled. It also uses a signed type to hold the
device count.
Provide a new API that is generally available, but marked as internal
since normally applications should not iterate over all devices. Mark
the PM API approach deprecated.

The dummy driver never implemented device power management, so the
fact the not-implemented stub returned success was a false negative.
Verify the expected behavior now, leaving the test code in place for
when somebody provides a non-trivial PM control function.

Device initialization may require use of generic services such as
starting up power rails, some of which may be controlled by GPIOs on
an external controller that can't be used until full kernel services
are available. Generic services can check k_is_in_isr() and mediate
their behavior that way, but currently have no way to determine that
the kernel is not available.
Provide a function that indicates whether initialization is still in
pre-kernel stages where no kernel services are available.

move misc/printk.h to sys/printk.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

device_get_binding() compares pointers first before doing strcmp().
However, enabling coverage forces -O0 to disable any compiler
optimizations. There would be multiple copies of the same string,
and the code pathing doing pointer comparsion would not be tested
at all. So add this flag to merge string constants such that
the pointer comparison would be exercised.
This also adds a bad driver which fails initialization. This is
to make sure that execution path is covered.

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.

Split the search into two loops: in the common scenario, where device
names are stored in ROM (and are referenced by the user with CONFIG_*
macros), only cheap pointer comparisons will be performed.
Reserve string comparisons for a fallback second pass.
