video: add support for Y212 format

Browse source 
Y212 is a packed 12 bits 4:2:2 format in the order Y, U, Y, V, 2 bytes
per component with the color value stored in the 12 most significant
bits

Refer to https://github.com/torvalds/linux/blob/master/include/uapi/drm/drm_fourcc.h#L174
for the LE variant
