Merge tag 'stm32-dt-for-v6.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/atorgue/stm32 into soc/dt

STM32 DT for v6.7, round 1

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

- MCU:
  - Add SDIO  sleep pins for F7 boards.

- MPU:
  - STM32MP13:
    - Add HASH and RNG support.

  - STMP32MP15:
    - OCTAVO:
      - Fix regulators (LDO1/2/6 and 3v3_hdmi) by removing "always-on"
        property on OSD32 common file.
      - Add new OS32MP1-RED board. It embeds a STM32157C SoC,
        512 MB of DDR3, CAN-FD, HDMI, USB-C OTG.

  - STM32MP25:
    - Add and enable SDCARD support.
    - Add and enable ARM watchdog support and set it to 32 seconds.
