ARM: dts: stm32: enable OV5640 camera on stm32mp157c-ev1 board 



Enable OV5640 camera sensor driver of MB1379A extension
board connected on CN7 connector of stm32mp157c-ev1 board:
bus-width is set to 8, data-shift is set to 2 (lines 9:2 are used),
hsync-active is set to 0 for horizontal synchro line active low,
vsync-active is set to 0 for vertical synchro line active low and
pclk-sample is set to 1 for pixel clock polarity sampling data
on rising edge of the pixel clock signal.
