HID: input: do not query XP-PEN Deco LW battery

Browse source

[ Upstream commit 037c1aaeb9 ]

The XP-PEN Deco LW drawing tablet can be connected by USB cable or using
a USB Bluetooth dongle. When it is connected using the dongle, there
might be a small delay until the tablet is paired with the dongle.

Fetching the device battery during this delay results in random battery
percentage values.

Add a quirk to avoid actively querying the battery percentage and wait
for the device to report it on its own.
