HID: add HP 13t-aw100 & 14t-ea100 digitizer battery quirks

Similar to many other devices using the Synopsys Designware Elantech
hardware, HP Spectre x360 13t-aw100 and 14t-ea100 report an empty
battery devices, supposedly for the active stylus.

Apply the HID_BATTERY_QUIRK_IGNORE quirk to ignore the battery reports
from these devices. Note that there are multiple versions of the panel
installed in the 14t-ea100.
