  This series works on the .s_stream, .enable_streams, .disable_streams
related code:

"media: subdev: Add checks for subdev features" adds check to verify
that the subdevs implement the proper mix of the above ops.

"media: subdev: Fix use of sd->enabled_streams in call_s_stream()" fixes
somewhat questionable use of sd->enabled_streams in call_s_stream().

"media: subdev: Improve v4l2_subdev_enable/disable_streams_fallback"
drops the restriction of supporting only a single source pads, and
prepares the way for the following patch.

"media: subdev: Support enable/disable_streams for non-streams subdevs"
makes it possible for non-streams subdevs to use .enable_streams and
.disable_streams, deprecating the earlier patch "[PATCH] media:
v4l2-subdev: Support enable/disable_streams for single-pad subdevs".

I have tested this on RPi5 with multiple streams, but I still need to
figure out ways to test the other scenarios.
