[PATCH] arm64: dts: st: add boot phase tags for Engicam MicroGEA-STM32MP257D-RMM

[Dario Binacchi <dario.binacchi@amarulasolutions.com>]

Add the bootph-all tag to the nodes used by the bootloader during the
early stages of bootup.

This includes the console UART with its pins and the display controller,
used for the splash screen.
