drm/vc4: Use .pixel_order instead of custom .flip_cbcr
The hardware has enums for altering the Cr and Cb order, so use this instead of having a flag which swaps the order the pointers are presented to the hardware (that only worked for 3 plane formats anyway). Explicitly sets .pixel_order in each case, rather than relying on then default XYCBCR order being a value 0.
