The Chicony Electronics HP 5MP Camera (USB ID 04F2:B82C) reports a HID
sensor interface that is not actually implemented. Attempting to access
this non-functional sensor via iio_info causes system hangs as runtime PM
tries to wake up an unresponsive sensor.
Add this device to the HID ignore list since the sensor interface is
non-functional by design and should not be exposed to userspace.
