drm/amd/display: Properly clear SCL_*_FILTER_CONTROL on DCE6

Browse Source 
[ Upstream commit c0aa7cf49d ]

Previously, the code would set a bit field which didn't exist
on DCE6 so it would be effectively a no-op.

Fixes: b70aaf5586 ("drm/amd/display: dce_transform: add DCE6 specific macros,functions")
