Userspace has no way of controlling or knowing the pixel encoding
currently, so there is no way for it to ever get the right values here.
When we do add pixel_encoding control from userspace,we can pick the
right value for the colorimetry packet based on the
pixel_encoding + the colorspace.
Let's deprecate these values, and have one BT.2020 colorspace entry
that userspace can use.
Note: _CYCC was effectively 'removed' by this change, but that was not
possible to be taken advantage of anyway, as there is currently no
pixel_encoding control so it would not be possible to output
linear YCbCr.
