Empty-Commit: Cherry-Pick Conflicts during history rebuild.
Will be included in final tarball splat. Ref for failed cherry-pick at:

The media bus configuration is specified through a set of flags, some of
which being mutually exclusive. This doesn't scale to express more
complex configurations. Improve the API by replacing the single flags
field in v4l2_mbus_config by a union of v4l2_mbus_config_* structures.
The flags themselves are still used in those structures, so they are
kept here. Drivers are however updated to use structure fields instead
of flags when already possible.
