drm/amd/display: use translate_curve_to_degamma_hw_format on DCN30

DCN3.01 presents the same banding issue as reported in the link below,
but the previous fix doesn't cover this hw. Change the helper used to
translate degamma/blend curves to HW points for DCN30, DCN 301, DCN31
and DCN314 similar to what was done for DCN32+ by commit 3719314af322
("drm/amd/display: use a separate helper to translate degamma curves").
