ARM: dts: stm32: phyboard-sargas and phycore: Add optional interfaces

- stm32mp15xx-phycore-som: add NAND device on FMC interface to support
the SoM version equipped with NAND flash instead of eMMC.

- stm32mp15xx-phyboard-sargas: define pinctrl for PWM5, LTDC and DCMI
interfaces used on phyBOARD-Sargas. Those interfaces are not enabled by
default as PHYTEC displays and PHYTEC cameras are enabled and configured
throught device tree overlays.
PWM5 is used for LCD backlight command.
