ARM: dts: stm32mp1: move FDCAN to PLL4_R

Browse source 
LTDC modifies the clock frequency to adapt it to the display. Such
frequency change is not detected by the FDCAN driver that instead
cache the value at probe and pretend to use it later.

Keep the LTDC alone on PLL4_Q by moving the FDCAN to PLL4_R.
