[ Upstream commit 3a47fa7b14c7d9613909a844aba27f99d3c58634 ]
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.
