DE3 supports 10-bit formats, so it's only naturally to also support
BT2020 encoding.
Add support for it.

YUV to RGB matrices are almost identical to YVU to RGB matrices. They
only have second and third column reversed. Do that reversion in code in
order to lower amount of static data and redundancy.

Rework DE3 CSC macros to take just one coordinate instead of two. This
will make its usage easier in subsequent commit.

Conversion from YUV to RGB depends on range (limited or full) and
encoding (BT.601 or BT.709). Current code doesn't consider this and
always uses BT.601 encoding and limited range.
Fix this by introducing new CSC matrices, which are selected based on
range and encoding parameters.

It turns out addition of 0x200 to constant parts (+0.5) is not really
necessary. Besides, we can consider that before and fix value in CSC
matrix.
This simplifies register writes quiet a bit.

Drop use of the deprecated drmP.h header file.
While touching the list of include file, use the typical order of the
blocks:
\#include <linux/*>
\#include <video/*>
\#include <drm/*>
\#include ""
Within each block, sort the files.
Include necessary files to fix build after the drmP.h removal.

Display Engine 3 is an upgrade of DE2 with new features like support for
10 bit color formats and support for AFBC.
Most of DE2 code works with DE3, except some small details.
Implement basic support for DE3. Support for 10 bit colort formats and
AFBC, among others missing features, will be added later.

DE2 have many CSC units - channel input CSC, channel output CSC and
mixer output CSC and maybe more.
Fortunately, they have all same register layout, only base offsets
differs.
Add support only for channel output CSC for now.
