Subject: [PATCH 5.4 246/411] media: coda: Fix reported H264 profile

From: Nicolas Dufresne <nicolas.dufresne@...labora.com>

commit 7110c08ea71953a7fc342f0b76046f72442cf26c upstream.

The CODA960 manual states that ASO/FMO features of baseline are not
supported, so for this reason this driver should only report
constrained baseline support.

This fixes negotiation issue with constrained baseline content
on GStreamer 1.17.1.

ASO/FMO features are unsupported for the encoder and untested for the
decoder because there is currently no userspace support. Neither GStreamer
parsers nor FFMPEG parsers support ASO/FMO.
