drm/amd/display: Properly clear SCL_*_FILTER_CONTROL on DCE6
[ Upstream commit c0aa7cf49dd6cb302fe28e7183992b772cb7420c ]
Previously, the code would set a bit field which didn't exist
on DCE6 so it would be effectively a no-op.
Fixes: b70aaf5586f2 ("drm/amd/display: dce_transform: add DCE6 specific macros,functions")
