AV1 hardware can only decode YUV420 pixel format. That means
that only profile 0 is supported. Discard all other profiles
when receiving AV1 sequence control.

You should also add the missing control to better tell userspace what it can and
cannot do. Check MTK driver for reference, I think the same config can be used:

drivers/media/platform/mediatek/vcodec/decoder/mtk_vcodec_dec_stateless.c
...
		.cfg = {
			.id = V4L2_CID_MPEG_VIDEO_AV1_PROFILE,
			.min = V4L2_MPEG_VIDEO_AV1_PROFILE_MAIN,
			.def = V4L2_MPEG_VIDEO_AV1_PROFILE_MAIN,
			.max = V4L2_MPEG_VIDEO_AV1_PROFILE_MAIN,
		},
...
