STM32 SoC for v5.16, round 1

Browse Source 
Highlights:
 ----------
 
 Add support of new STM32MP13 SoC which enhances current
 STM32 MPU family. It is mainly a derivative of STM32MP15 SoCs
 (one Cortex-A7 plus standard peripherals).
 
 The STM32MP13 SoC diversity is composed by:
     -STM32MP131:
       -core: 1*CA7, 17*TIMERS, 5*LPTIMERS, DMA/MDMA/DMAMUX
       -storage: 3*SDMCC, 1*QSPI, FMC
       -com: USB (OHCI/EHCI, OTG), 5*I2C, 5*SPI/I2S, 8*U(S)ART
       -audio: 2*SAI
       -network: 1*ETH(GMAC)
     -STM32MP133: STM32MP131 + 2*CAN, ETH2(GMAC), ADC1
     -STM32MP135: STM32MP133 + DCMIPP, LTDC

The STM32MP131/STM32MP133/STM32MP135 are Cortex-A MPU aimed at various applications.
They feature:
- One Cortex-A7 application core
- Standard memories interface support
- Standard connectivity, widely inherited from the STM32 MCU family
- Comprehensive security support
More details:
- Cortex-A7 core running up to @900MHz
- FMC controller to connect SDRAM, NOR and NAND memories
- QSPI
- SD/MMC/SDIO support
- 2*Ethernet controller
- CAN
- ADC/DAC
- USB EHCI/OHCI controllers
- USB OTG
- I2C, SPI, CAN busses support
- Several general purpose timers
- Serial Audio interface
- LCD controller
- DCMIPP
- SPDIFRX
- DFSDM
