[ Upstream commit c06bc3557542307b9658fbd43cc946a14250347b ]

Another Chicony Electronics HP 5MP Camera with USB ID 04F2:B882
reports a HID sensor interface that is not actually implemented.

Add the device to the HID ignore list so the bogus sensor is never
exposed to userspace. Then the system won't hang when runtime PM
tries to wake the unresponsive device.
