HID: input: avoid polling stylus battery on Chromebook Pompom 

[ Upstream commit 9a5b1521e2 ]

Internal touchscreen on Trogdor Pompom (AKA Dynabook Chromebook C1)
supports USI stylus. Unfortunately the HID descriptor for the stylus
interface does not contain "Stylus" physical collection, which makes
the kernel to try and pull battery information, resulting in errors.

Apply HID_BATTERY_QUIRK_AVOID_QUERY to the device.
