drm/colorop: Add 3x4 CTM type
This type is used to support a 3x4 matrix in colorops. A 3x4
matrix uses the last column as a "bias" column. Some HW exposes
support for 3x4. The calculation looks like:
out matrix in
|R| |0 1 2 3 | | R |
|G| = |4 5 6 7 | x | G |
|B| |8 9 10 11| | B |
|1.0|
This is also the first colorop where we need a blob property to
program the property. For that we'll introduce a new DATA
property that can be used by all colorop TYPEs requiring a
blob. The way a DATA blob is read depends on the TYPE of
the colorop.
We only create the DATA property for property types that
need it.
