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.
