Add three new formats storing packed YUV 4:4:4 in 10-, 12- and 16-bpc
variants, with component order VUY. They are used by the Xilinx Video
Frame Buffer Read/Write IP cores.

+The next table lists the packed YUV 4:4:4 formats with more than 8 bits per
+component. They are named similarly to the formats with less than 8 bits per
+components, based on the order of the Y, Cb and Cr components as seen in a

+number of bits for each component. The component names and the corresponding
