drm/amd/display: bypass post csc for additional color spaces in dal

Browse source

[ Upstream commit 7d9ec9dc20 ]

[Why]
For RGB BT2020 full and limited color spaces, overlay adjustments were
applied twice (once by MM and once by DAL). This results in incorrect
colours and a noticeable difference between mpo and non-mpo cases.

[How]
Add RGB BT2020 full and limited color spaces to list that bypasses post
csc adjustment.
