Subject: [PATCH 00/17] Improve DE2 support

Current DE2 driver is very basic and uses a lot of magic constants since
there is no documentation and knowledge about it was limited at the time.

With studying BSP source code, deeper knowledge was gained which allows
to improve mainline driver considerably.

At the beginning of this series, some code refactoring is done as well
as adding some checks (patches 1-5).

Further patches add multi-plane support with HW scaling and all possible
RGB formats (patches 6-11).

At last, support for YUV formats is added (patches 12-16).

At the end, I included patch which puts lowest plane before second lowest.
This should help testing VI planes when mixer has configuration 1 VI plane
and 1 on more UI planes (most SoCs except V3s).

This code was developed on H3, but it should work on every SoC if correct
configuration structure is provided.

H3 code can be found here:
