This patch add support for Bananapi S070WV20-CT16 panel to BPI-M2M board.
Bananapi S070WV20-CT16 is a pure RGB output panel with ICN6211 DSI/RGB converter bridge, so enable bridge along with associated panel.
DSI panel connected via board DSI port with, - DCDC1 as VCC-DSI supply - PL5 gpio for bridge enable gpio pin - PB7 gpio for lcd enable gpio pin - PL4 gpio for backlight enable pin
