drm/vc4: hdmi: Swap CSC matrix channels for YUV444

Browse source

YUV444 and YUV422 actually require the same matrix, but programmed
differently.

We've dealt with it in the past by having two matrices, with the one
for YUV444 reordered to accomodate the hardware.

This gets in the way of subsequent reworks so let's define a function
that will take the coefficients swap into account, and remove the now
redundant YUV444 matrix.
