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.
