From: Alexandre Torgue <alexandre.torgue@xxxxxxxxxxx>
STM32MP21 family is composed of 3 SoCs defined as following:
-STM32MP211: common part composed of 1*Cortex-A35, common peripherals
like SDMMC, UART, SPI, I2C, parallel display, 1*ETH ...
-STM32MP213: STM32MP211 + a second ETH, CAN-FD.
-STM32MP215: STM32MP213 + Display and CSI2.
A second diversity layer exists for security features/ A35 frequency:
-STM32MP21xY, "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.

Changes in v2:
- Comply with DTS coding style
- interrupt-controller node moved under soc node
