drm/amd/display: Implement bias and scale pre scl

why:
New scaler needs the input to be full range color space. This will also fix
issues that come up due to not having a predefined limited color space matrix
for certain color spaces

how:
Use bias and scale HW to expand the range of limited color spaces to full
before the scaler
