Subject: [PATCH v8 7/9] ARM: sun8i: v3s: add device nodes for DE2 display pipeline

Allwinner V3s SoC features a "Display Engine 2.0" with only one mixer
and only one TCON connected to this mixer, which have RGB LCD output.

Add device nodes for this display pipeline.

Signed-off-by: Icenowy Zheng <icenowy@...c.io>

Changes in v8:
- Changed some label names.
Changes in v7:
- Change DE2 clock compatible to V3s one.
- Mention only one TCON in commit message.
- Changed commit brief.
