media: v4l: fwnode: Add a convenience function for registering sensors
Add a convenience function for parsing firmware for information on related
devices using v4l2_async_notifier_parse_fwnode_sensor_common() registering
the notifier and finally the async sub-device itself.
This should be useful for sensor drivers that do not have device specific
requirements related to firmware information parsing or the async
framework.
