HID: amd_sfh: Add a new interface for exporting ALS data
AMDSFH has information about the Ambient light via the Ambient
Light Sensor (ALS) which is part of the AMD sensor fusion hub.
Add a new interface to export this information, where other drivers like
PMF can use this information to enhance user experiences.
