HID: hid-input: add Surface Go battery quirk
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.
