media: v4l2-fwnode: Move bus config structure to v4l2_mediabus.h
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.
