Only give "pixel_format=nv12" option to v4l2m2m or v4l2requests decoders

Browse source 
pixel_format is a global option which changes avctx->pix_fmt to the
given format, and overrides the AV_PIX_FMT_DRM_PRIME requirement of a
decoder. So v4l2 out of tree patches has done some exception which is
not perfectly nice, therefore limit this option only if the given
decoder is v4l2 decoder. Otherwise rockchip mpp based ffmpeg decoders
can not work properly
