drm/i915/tgl+: Add the missing MC CCS/XYUV8888 format support 



Make sure that the XYUV8888 format is handled correctly when it's used
with a MC_CCS modifier framebuffer. Besides this format not working, the
driver will also return an incorrect error value when trying to use it,
indicating that the second color plane in the framebuffer is set
unexpectedly.
