The "Display Engine 2.0" in Allwinner newer SoCs contains a clock
management unit for its subunits, like the DE CCU in A80.
Add a sunxi-ng style driver for it.

A 480x272 QiaoDian QD43003C0-40-7LED panel is available from Lichee Pi.
This commit connects this panel to Lichee Pi Zero.
Lichee Pi also provides a 800x480 panel without accurate model number,
so do not merge this patch. It will finally come as device tree overlay.

Allwinner have a new "Display Engine 2.0" in there new SoCs, which comes
in a new "Display Engine" (mixers instead of old backends and
frontends).
Add support for the mixer on Allwinner V3s SoC; it's the simplest one.
