libcamera: camera_sensor: Print warning when orientation is unknown

Browse source 
Print a warning when the orientation of a sensor is unknown. The
location property is still defaulted to external.

Also add a recommended controls list, similar to the optional and
mandatory controls list, to handle controls in a similar situation in
the future.
