hwdec_drmprime: add nv16 support

Browse Source 
NV16 is the half subsampled version of NV12 format. Decoders which
support High 4:2:2 of h264 provide the frame in NV16 format to establish
richer colorspace. Similar profiles are also available in HEVC and other
popular codecs. This commit allows NV16 frames to be displayed over
drmprime layers.
