STM32 DT for v6.6, round 1

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

- MCU:
  - Add CAN support on stm32f746.
  - Add touchscreen support (edt-ft5306) on stm32f746-disco.
  - Add support to Rocktech RK043FN48H display on stm32f746-disco
    board.
  - Add gpio-ranges for stm32f7 to fix boot issue.

- MPU:
  - STM32MP13:
    - Remove shmem for scmi-optee to match with OP-TEE configuration.
    - Enable OP-TEE asynchronous notification by using PPI#15.
    - Expose and use SCMI regulators on stm32mp135f-dk.

  - STMP32MP15:
    - Remove shmem for scmi-optee to match with OPTEE configuration
    - Deduplicate DSI node to fix  #address-cells/#size-cells issue on
      boards using it.

  - ST:
    - Fix dts check warnings on stm32mp15-scmi boards.

  - DH:
    - Add missing detach mailbox for DHCOM and DHCOR SoM.

  - Odyssey:
    - Add missing detach mailbox for Odyssey SoM.

  - OCTAVO:
    - Add Linux Automation Test Automation Controller (LXA TAC) based
      on Octavo Systems OSD32MP15x SiP. It contains: eMMC,
      DSA-capable ETH switch (2 ports), dual CAN...
      It adds two boards support: lxa-tac-gen1 and lxa-tac-gen2 based
      on STM32MP157.

  - PROTONIC:
    - Add Power over Data Line (PoDL) Power Source Equipment (PSE)
      regulator nodes on PRTT1C board. It allows power delivery and
      data transmission over a single twisted pair.
