    HID: quirks: Add quirk for 2 Chicony Electronics HP 5MP Cameras

    The Chicony Electronics HP 5MP Cameras (USB ID 04F2:B824 & 04F2:B82C)
    report 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 these 2 devices to the HID ignore list since the sensor interface is
    non-functional by design and should not be exposed to userspace.
