Empty-Commit: Cherry-Pick Conflicts during history rebuild.
Will be included in final tarball splat. Ref for failed cherry-pick at:
ciq/ciq_backports/kernel-5.14.0-570.22.1.el9_6/94d964e5.failed

To prepare for usage of the v4l2_fwnode_bus_* data structures to
describe bus configuration in the subdev .get_mbus_config() operation,
rename the structures with a v4l2_mbus_config_ prefix instead of
v4l2_fwnode_bus_, and move them to v4l2_mediabus.h.
