Subject: HID: usbhid: quirk for SiS Touchscreen

commit 684524d35fe8d13be1f2649633e43bd02c96c695 upstream.

BugLink: http://bugs.launchpad.net/bugs/1180881

This device needs to be added to the quirks list with HID_QUIRK_NO_INIT_REPORTS,
otherwise it causes 10 seconds timeout during report initialization.
