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.

drivers: stm32_rstctrl reset controller for stm32mp1 platforms

Implement stm32 platforms reset controller device, embedded upon
CFG_STM32_RSTCTRL=y.

The drivers exposes its reset controls to the dt_driver provider and
with stm32mp1 platform legacy reset control API function:
stm32_reset_assert(), stm32_reset_deassert() and
stm32_reset_assert_deassert_mcu().

This change also removes source file stm32mp1_rcc.c that has moved
to drivers/rstctrl/stm32_rstctrl.c but stm32_rcc_base() definition
which is moved into to platform main.c.

drivers: add reset controller framework

Adds a common reset controller framework rstctrl for interfacing
reset controllers exposed by a platform.

Reset controller consumers can act on relate reset level with
rstctrl_assert(), rstctrl_deassert() and friends.

Reset controller consumers can claim exclusive access to the reset
level woth rstctrl_get_exclusive(), rstctrl_put_exclusive().

Reset controller provider drivers call rstctrl_register_provider()
to allow other drivers to get a reset control reference from
a devicetree reference. Reset controller driver are identified with
type DT_DRIVER_RSTCTRL.

A reset controller provider exposes struct rstctrl instances made of
an opaque private reference (a private data pointer or an unsigned
integer identifier), an reset controller operators reference and
the exclusive claim state.
