For the Processing Unit and Camera Terminal descriptors defined in the UVC Gadget we currently hard-code values into their bmControls fields, which enumerates which controls the gadget is able to support. This isn't appropriate since only the userspace companion program to the kernel driver will know which controls are supported. Make the configfs attributes that point to those fields read/write so userspace can set them to appropriate values. Document the new behaviour at the same time so the functionality is clear.
