HID: hid-input: add Surface Go battery quirk
commit db925d809011c37b246434fdce71209fc2e6c0c2 upstream.
Similar to the Surface Go (1), the (Elantech) touchscreen/digitizer in
the Surface Go 2 mistakenly reports the battery of the stylus. Instead
of over the touchscreen device, battery information is provided via
bluetooth and the touchscreen device reports an empty battery.
Apply the HID_BATTERY_QUIRK_IGNORE quirk to ignore this battery and
prevent the erroneous low battery warnings.
