[PATCH 12/12] arm64: dts: allwinner: bananapi-m64: Bananapi S070WV20-CT16 DSI panel

[Jagan Teki]

This patch add support for Bananapi S070WV20-CT16 DSI panel to
BPI-M64 board.

DSI panel connected via board DSI port with,
- DC1SW as AVDD supply
- DCDC1 as DVDD supply
- PD6 gpio for reset pin
- PD5 gpio for backlight enable pin
- PD7 gpio for backlight vdd supply
