CCS CC planes are quite different from CCS control planes, even though
we regard the CC planes as a linear buffer having a 64 byte stride.
Thus it's clearer to check for either CCS plane types explicitly when we
need to handle them; add the required CCS CC planes check here, while
the next patch will change all is_ccs_plane()/is_gen12_ccs_plane()
checks to consider only the CCS control planes.
