P010 is a planar 4:2:0 YUV with interleaved UV plane, 10 bits per
channel video format.
P012 is a planar 4:2:0 YUV 12 bits per channel
P016 is a planar 4:2:0 YUV with interleaved UV plane, 16 bits per
channel video format.
V3: Added P012 and fixed cpp for P010.
V4: format definition refined per review.
V5: Format comment block for each new pixel format.
V6: reversed Cb/Cr order in comments.
v7: reversed Cb/Cr order in comments of header files, remove
the wrong part of commit message.
V8: reversed V7 changes except commit message and rebased.
v9: used the new properties to describe those format and
rebased.
