[0/9] drm: Add DSI/DP support for Renesas r8a779h0 V4M and grey-hawk board

Message

Add everything needed to support the DSI output on Renesas r8a779h0
(V4M) SoC, and the DP output (via sn65dsi86 DSI to DP bridge) on the
Renesas grey-hawk board.

Overall the DSI and the board design is almost identical to Renesas
r8a779g0 and white-hawk board.

Woot, SoB tags for cover letters ;-)

Works fine up to 2560x1440 (I don't have a 4K display).
