HID: Recognize "Digitizer" as a valid input application

"Digitizer" is a generic usage that may be used by various devices but
which is particularly used by non-display pen tablets. This patch adds the
usage to the list of values matched by the IS_INPUT_APPLICATION() macro
that determines if an input device should be allocated or not.
