This change prepares the STM32MP25 reset controller driver.
The binding for the STM32MP25 is different from that of the
STM32MP1x, so we will create a stm32mp25_rstcrl.c file.
This change factorizes STM32 API functions in stm32_rstcrl.c file
for probing and passing platform data.

core: dt_driver: swap TEE_result and retrieved device reference

Changes dt_driver callback function to return a TEE_Result value
and pass retrieved device reference by a output argument rather
than the opposite.

This change updates dt_driver.c, dt_driver.h and all drivers
implementing related dt_driver callback function.

As a consequence, this change removes all type definition related
to device specific callback handler function types which are useless
as all these now comply with type dt_driver_probe_func defined in
dt_driver.h.
