e46aff5902 drivers: rtc: stm32: avoid using LL_RTC_Init
LL_RTC_Init() internally uses LL_RTC_EnterInitMode() wich uses a blocking
while loop. This rewrite uses the less CPU time wasteful local
rtc_stm32_enter_initialization_mode() instead. As a side effect
LL_RTC_InitTypeDef in rtc_stm32_config is not needed anymore.

That's correct. We are still fixing the Y2K bug in 2023 \o/

* write century to RAM register 0x32
* ensure year register is in [0,99] (inclusive)

Aside from that, there were a few other errors in the driver.

* translate epoch-centric RTC API year to begin at 1900
* fix off-by-one error with month limit
* fix off-by-one error with wday
* fix off-by-one-hundred error with year limit
* adjust timeptr values in rtc_mc146818_validate_time()
* adjust timeptr values in rtc_mc146818_validate_alarm()

With the above, the testsuite passes!

b557a1d711 include/drivers: Add RTC API header and handlers
This commit adds the rtc.h header file which contains
API functions for real-time-clocks, which are low power
devices which track and represent broken-down time.

It also changes one line of doxygen documentation in the
maxim_ds3132.h file to place it in its own group.

The handlers for use of the API from userspace is also
added with this commit.

The API is split into one mandatory section, setting and
getting time, and three optional sections, alarms, update
event callback, and clock calibration.

075c94f6e2 kernel: Port remaining syscalls to new API
These calls are not accessible in CI test, nor do they get built on
common platforms (in at least one case I found a typo which proved the
code was truly unused).  These changes are blind, so live in a
separate commit.  But the nature of the port is mechanical, all other
syscalls in the system work fine, and any errors should be easily
corrected.

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

a51a7817cf kconfig: drivers: rtc: Remove redundant RTC deps.
These symbols appear within an 'if RTC' (in drivers/rtc/Kconfig).

'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. Dependencies on menus work similarly. 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.
