[media] v4l: Add V4L2_PIX_FMT_NV16M and V4L2_PIX_FMT_NV61M formats
NV16M and NV61M are planar YCbCr 4:2:2 and YCrCb 4:2:2 formats with a
luma plane followed by an interleaved chroma plane. The planes are not
required to be contiguous in memory, and the formats can only be used
with the multi-planar formats API.
