I'd prefer to be explicit here. The list of supported formats might
vary between generations, might it not? Also we don't have a case of
the devices not having VIG planes. Even the qcm2290 (which doesn't
have CSC) lists YUV as supported.
Note: I think at some point we should have a closer look at the list
of supported formats and crosscheck that we do not have either
unsupported formats being listed, or missing formats which are not
listed as supported.
