Subject: [PATCH 1/1] HID: uclogic: Add HID_QUIRK_HIDINPUT_FORCE quirk

Commit f7d8e387d9ae ("HID: uclogic: Switch to Digitizer usage for
styluses") changed the usage used in UCLogic from "Pen" to "Digitizer".

However, the IS_INPUT_APPLICATION() macro evaluates to false for
HID_DG_DIGITIZER causing issues with the XP-Pen Star G640 tablet.

Add the HID_QUIRK_HIDINPUT_FORCE quirk to bypass the
IS_INPUT_APPLICATION() check.
