9f9625ea80 kmsgrab: Remove multiple-plane formats 
The planes are unlikely to be contiguous, assuming they are results in
very broken output.  (Tested with NV12/NV16 on Rockchip.)

22afa87a8e kmsgrab: Fix DRM format definitions 
All DRM formats are defined in terms of little-endian words, so RGB formats
like XRGB actually have the elements in the opposite order order in memory
to the order they are in the name.

This does not affect YUYV and similar YUV 4:2:2 formats, which are in the
expected order.
