Add the LTDC node for stm32mp235 SoC and handle its loopback clocks.
ck_ker_ltdc has the CLK_SET_RATE_PARENT flag. While having this flag is
semantically correct, it for now leads to an improper setting of the
clock rate. The ck_ker_ltdc parent clock is the flexgen 27, which does
not support changing rates yet. To overcome this issue, a fixed clock
can be used for the kernel clock.

stm32mp25-pinctrl.dtsi gathers all pinctrl groups from current and future
STM32MP25-based boards. Some groups may remain unused by any board,
resulting in wasted binary space.
Adding /omit-if-no-ref/ to the groups will remove unused groups from the
device tree blobs.
Use the following regex to update the file:
's/^\t[^:]\+: [^ ]\+ {$/\t\/omit-if-no-ref\/\n&/'
Also, merge the duplicated pinctrl_z node.

In order to set the AMCR register, which configures the
memory-region split between ospi1 and ospi2, we need to
identify the ospi instance.
By using memory-region-names, it allows to identify the
ospi instance this memory-region belongs to.
