HID: input: Set INPUT_PROP_-property for HID_UP_DIGITIZERS

Some system may want to know if a detected digitizer device is either an
integrated or an external device. In order to distinguish such condition,
setting either INPUT_PROP_DIRECT or INPUT_PROP_POINTER is required,
checking the member, "application", in "hid_field" structure.
