  -Add I2C fatmode plus support

 -Add new Octavio lxa-mc1 board based on OSDMP15x SiP

 -Add new Stinger96 board support. It is a 96Boards IoT Extended board
  based on stm32mp157a SoC. Some figures: 256MB DDR, 125MB and flash,
  Onboard BG96 modem...

 -Add IoT Box board support based on stinger96 board + Wifi/BT, CCS811
  VOC sensor, 2 digitals microphones ...

 -DH:
  -Adapt dhcom-som and dhcom-pdk2 dts(i) files to STM32MP15 SoC diversity
  -Add GPIO led and GPIO keys support on PDK2 board

 -AV96:
