video: add support for Y412 format

Browse source 
Y412 is a packed 12 bits 4:4:4:4 format in the order U, Y, V, A, 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#L182
for the LE variant
