Subject: [PATCH] media: hantro: Support H264 profile control

The Hantro G1 decoder supports H.264 profiles from Baseline to High, with
the exception of the Extended profile.

Expose the V4L2_CID_MPEG_VIDEO_H264_PROFILE control, so that the
applications can query the driver for the list of supported profiles.
