STM32 SoC for v5.16, round 1
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
