arm64: dts: st: add ltdc support on stm32mp235

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.
