From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
We can simplify the vlv watermark sanitation by reusing the
second half of vlv_compute_pipe_wm() to convert the sanitized
raw watermarks into the proper form to be used as the
optimal/intermediate watermarks.
Also to be consistent with normal watermark computation the sanitized
watermarks should be all 0 for any disabled plane. Previously we
zeroed out the watermarks only up to the level (ie. PM2/5/DVDFS)
that was enabled.
