 -Add STMFX support en stm32mp157c-ev1 and enable joystick connected on
  it.
 -Add I2S and SAI support on stm32mp157c.
 -Add and enable support of Vivante GPU on stm32mp157 ED1 and DK1 boards
  (EV1 and DK2 inherit of it).
 -Add camera support:
  -Add DCMI support on stm32mp157c SOC
  -Enabled OV5640 camera support on stm32mp157c-ev1 board
 -Enable hdmi bridge sii9022 & display controller on stm32mp157c-dk1
  board.

MCU part:
