[RFC PATCH 10/11] ARM: sun8i: h3: add display engine pipeline for TVE

[Icenowy Zheng]

As we have already the support for the TV encoder on Allwinner H3, add
the display engine pipeline device tree nodes to its DTSI file.

The H5 pipeline has some differences and will be enabled later.

The currently-unused mixer0 and tcon0 are also needed, for the
completement of the pipeline.
