HID: add Lenovo Yoga C630 battery quirk 



Similar to the Surface Go devices, the Elantech touchscreen/digitizer in
the Lenovo Yoga C630 mistakenly reports the battery of the stylus, and
always reports an empty battery.

Apply the HID_BATTERY_QUIRK_IGNORE quirk to ignore this battery and
prevent the erroneous low battery warnings.
