[ Upstream commit b5539722eb ]
The Elantech touchscreen/digitizer in the Surface Go mistakenly reports
having a battery. This results in a low battery message every time you
try to use the pen.
This patch adds a quirk to ignore the non-existent battery and
gets rid of the false low battery messages.
