Subject: [PATCH v2 14/15] arm64: dts: allwinner: a64: Add DSI pipeline

The A64 has a MIPI-DSI block which is similar to A31
without mod clock.

So, add dsi node with A64 compatible, dphy node with
A31 compatible and finally connect dsi to tcon0 to
make proper DSI pipeline.

Signed-off-by: Jagan Teki <jagan@...rulasolutions.com>

Changes for v2:
- use A64 dphy compatible
