dts: stm32: introduce STM32MP25 SoCs family

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.

Available packages are:

STM32MP25xAI: 18*18/FCBGA 172 ios
STM32MP25xAK: 14*14/FCBGA 144 ios
STM32MP25xAL: 10*10/TFBGA 144 ios

core: ffa: fix spmc_retrieve_req() buffer

Prior to this patch when retrieving a shared memory block the memory
transaction descriptor (struct ffa_mem_transaction_1_1 or struct
ffa_mem_transaction_1_0) was read from the TX buffer instead of the RX
buffer where the actual memory transaction is supplied. Fix this by
changing to read the memory transaction descriptor from the RX buffer.

This used to work somewhat by chance since OP-TEE before the call to
FFA_MEM_RETRIEVE_REQ_32 filled in a memory transaction descriptor
of what we expect to retrieve in the TX buffer.
