HID: uclogic: Add battery quirk

Browse Source 
[ Upstream commit f60c377f52de37f8705c5fc6d57737fdaf309ff9 ]

Some UGEE v2 tablets have a wireless version with an internal battery
and their firmware is able to report their battery level.

However, there was not found a field on their descriptor indicating
whether the tablet has battery or not, making it mandatory to classify
such devices through the UCLOGIC_BATTERY_QUIRK quirk.
