media: Add P012 and P012M video format
P012 is a YUV format with 12-bits per component with interleaved UV, like NV12, expanded to 16 bits. Data in the 12 high bits, zeros in the 4 low bits, arranged in little endian order. And P012M has two non contiguous planes. Signed-off-by: Ming Qian <ming.qian@nxp.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
