va: Allow attribute-by-attribute configuration of the TCC filter

A VA buffer can hold several total color correction attributes
by creating a VA buffer of the desired number of elements, in
such a way that you can independently modify the attribute or
attributes (out of R, G, B, C, M and Y) that you need.
