[PATCH] HID: Ignore battery for ELAN touchscreens 2F2C and 4116 on ASUS Zenbook 14 OLED (2023) and ASUS Zenbook Pro 14 OLED (2023)

[Louis Dalibard <louis.dalibard@xxxxxxxxx>]

The touchscreen reports a battery status of 0% and jumps to 1% when a
stylus is used.
The device ID was added and the battery ignore quirk was enabled for it.
