Subject[PATCH v3 23/25] arm64: dts: allwinner: a64: Add DSI pipeline
Date
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.

Changes for v3:
- add allwinner,tcon-channel property
- add dsi nodes in ascending physical address
Changes for v2:
- use A64 dphy compatible
