[PATCH v4 09/11] ARM: dts: sun8i: add DE2 nodes for V3s SoC

[Icenowy Zheng]

Allwinner V3s SoC features a "Display Engine 2.0" with only one TCON
which have RGB LCD output.

Add device nodes for it as well as the TCON.

Changes in v4:
- Dropped leading 0's in unit name.
Changes in v3:
- Change the size of de2_clocks regs according to the binding example.
