YUV formats require only CSC to be enabled. Even decimated formats
should not require scaler. Relax the requirement and don't check for the

Change seems fine, but one question, is there a chipset in the catalog
with a Vig SSPP which has only csc but not scaler? Even qcm2290 has
neither scaler nor csc
So was this just a code-walkthrough fix or was there any issue hit due
to this?
Just a code walkthrough.
Alright,
