[DO NOT MERGE] [PATCH v2 9/9] ARM: dts: sun8i-r40: bananapi-m2-ultra: Enable Bananapi S070WV20-CT16 DSI panel

[Jagan Teki <jagan-dyjBcgdgk7Pe9wHmmfpqLFaTQe2KTcn/@public.gmane.org>]

This patch add support for Bananapi S070WV20-CT16 DSI panel to
BPI-M2U board.

DSI panel connected via board DSI port with,
- DCDC1 as VCC-DSI supply
- PH18 gpio for lcd enable pin
- PD17 gpio for lcd reset pin
- PD16 gpio for backlight enable pin
