This PR fixes the issue that building the driver with either
CONFIG_RTC_CALIBRATION=y or CONFIG_RTC_ALARM=y and without
'int-gpios' used will cause
'undefined reference to `rv8803_write_reg8'' error.

The #64939 introduced a few convenience function like
rtc_utils_validate_rtc_time. However the PR did not replace all
occurrences which result on a build error. This add the missing
header include to remove a building warning and replace the old
function by the new one.
Fixes#81454

We read/modify/write the CH/SECONDS register at initialisation to clear
only the Clock Halt bit and only if it is set.
The previous implementation zeroes the entire register unconditionally at
initialisation, which wipes the SECONDS fields.
Fixes#77354.

Added NXP IRTC Driver support and binding.
This driver is expected for users needing
Time Date info in their application.
The driver additionally has an alarm mode that
can be enabled to fire an intterupt when the time
and alarm values match.

Adds support for settings/getting RTC time and using alarm/update feature.
The alarm option needs all fields to be set due to a hardware limitation.
RTC shares the same interrupt with the watchdog. Thus shared
interrupts must be enabled when WDT and RTC both need to trigger the ISR.

Add support for HSE as the RTC clock source.
The initial implementation has the following limitations:
- Only whole MHz HSE frequency is supported, e.g. 24.5 MHz will generate a
compile error.
- Frequencies equal or above 64 MHz are not supported and will generate a
compile error.
The implementation has been tested on nucleo_h563zi with:
- 8 MHz (via hse-bypass)
- 25 MHz (via external crystal)

Fixing 3 issues:
1. The mask can be wrong if the alarm register is
set to a MAX value because the alarm bit is the
highest in the alarm register. The mask is now
generated by checking the AE_x bits in the time
registers.
2. Fixing possible NULL pointer exception in
alarm_set_time API. timeptr can be set to NULL
with mask 0 in the alarm_set_time function.
The regs variable for the I2C communication
is written with the correct value from timeptr
only when the right bit in the mask is set.
3. rv8263c8_alarm_set_time() now resets the
alarm status.
4. Interrupts are now enabled by using
rv8263c8_alarm_set_time() rather than when
setting an alarm callback.

Replace DIV_ROUND_CLOSEST() with a normal division to simplify
operation and avoid redundant handling of signed integer rounding
as the temp value is an unsigned value. The temp value is in nano
precision, so rounding is largely inconsequencial anyway compared
to the comparatively low precision sync prescaler.

This commit addresses the issue related to the rtc.h API returning ENOSYS
for a driver not implementing alarm_set_callback when the ALARM
functionality is enabled but interrupts, and thus alarm callbacks, are not
supported by the current configuration.

- rtc_pcf8523
- rtc_pcf8563
- rtc_rv3028

Namespaced the generated headers with `zephyr` to prevent
potential conflict with other headers.
Introduce a temporary Kconfig `LEGACY_GENERATED_INCLUDE_PATH`
that is enabled by default. This allows the developers to
continue the use of the old include paths for the time being
until it is deprecated and eventually removed. The Kconfig will
generate a build-time warning message, similar to the
`CONFIG_TIMER_RANDOM_GENERATOR`.
Updated the includes path of in-tree sources accordingly.
Most of the changes here are scripted, check the PR for more
info.

This commit should fix the followings:
1. When an alarm event is initialized, the driver should only
consume the valid alarm fields, based on the given mask.
Otherwise, the driver should use default valid subfield
values.
2. Setting an alarm event should not return with error code
if the timer and/or calendar counters have yet to be
initialized, explicitly. Instead, a log warning should be
issued.
