Subject: [DO NOT MERGE] [PATCH v2 2/6] ARM: dts: sun8i: bananapi-m2m: Enable Bananapi S070WV20-CT16 DSI panel

This patch add support for Bananapi S070WV20-CT16 DSI panel to
BPI-M2M board.

DSI panel connected via board DSI port with,
- DCDC1 as VCC-DSI supply
- PL5 gpio for lcd reset gpio pin
- PB7 gpio for lcd enable gpio pin
- PL4 gpio for backlight enable pin
