[PATCH RFC 1/5] media: uapi: videodev2: Add support for AV1 stateful decoder

[DEEPA GUTHYAPPA MADIVALARA <deepa.madivalara@oss.qualcomm.com>]

Introduce a new pixel format, V4L2_PIX_FMT_AV1, to the
Video4Linux2(V4L2) API. This format is intended for AV1
bitstreams in stateful decoding/encoding workflows.
The fourcc code 'AV10' is used to distinguish
this format from the existing V4L2_PIX_FMT_AV1_FRAME,
which is used for stateless AV1 decoder implementation.
