STM32 STM32MP25 for v6.5, round 1

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

STM32MP25 family is composed of 4 SoCs defined as following:

  -STM32MP251: common part composed of 1*Cortex-A35,
   common peripherals like SDMMC, UART, SPI, I2C, PCIe, USB3,
   parallel and DSI display, 1*ETH ...

  -STM32MP253: STM32MP251 + 1*Cortex-A35 (dual CPU), a second ETH,
   CAN-FD and LVDS display.

  -STM32MP255: STM32MP253 + GPU/AI and video encode/decode.
  -STM32MP257: STM32MP255 + ETH TSN switch (2+1 ports).

  A second diversity layer exists for security features/A35 frequency:
  -STM32MP25xY, "Y" gives information:
    -Y = A means A35@1.2GHz + no cryp IP and no secure boot.
    -Y = C means A35@1.2GHz + cryp IP and secure boot.
    -Y = D means A35@1.5GHz + no cryp IP and no secure boot.
    -Y = F means A35@1.5GHz + cryp IP and secure boot.

This PR adds the STM32MP257F EV1 board support. This board embeds a
STM32MP257FAI SoC, with 4GB of DDR4, TSN switch (2+1 ports),
2*USB typeA, 1*USB2 typeC, SNOR OctoSPI, mini PCIe, STPMIC2 for power distribution ...
