STM32 DT updates for v5.6, round 1

Highlights:
----------

MPU part:
 -Add PWM support on DK2 board.
 -Add counter support to STM32 timers.
 -Add support of SDMMC 2&3 instances based on "arm,pl18x". SDMMC2 is
  connected to eMMC on ED1 board. SDMMC3 is connected to the GPIO
  extension connector on EV1 & DKx boards.
 -Add ADC support on ED1 board.
 -Update devicetree files split to better fit to STM32MP15 SOC & boards
  diversity.
 -Fix issues seen during YAML validation.
 -Enable Ethernet (MAC) TX clock gating during low-power mode.
 -Enable USB OTG HS support on DKx boards.
 -Enable USB Host EHCI on DKx boards.

MCU part:
 -Fix issues seen during YAML validation.
