[v2,00/10] Add STM32MP25 support

I'm pleased to announce extension of the STM32 MPU family with the addition of
the STM32MP25 Armv8 based SoCs.

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 series 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 ...

Changes since v1:

-Add Conor "reviewed-by".
-Drop patch[4] of initial series to not define SoC without board in stm32,yaml.
-Add Krzysztof "Acked-by" after reordering enum in st,stm32-syscon.yaml

Thanks
Alex
