Subject: [PATCH] HID: add support for PenMount dual-touch panel
This patch adds PenMount support to hid-multitouch.
A new class MT_CLS_CONFIDENCE_SERIAL_MODE is defined for PenMount,
since it uses HID_DG_CONFIDENCE as the valid flag.
A new quirk MT_QUIRK_SERIAL_REPORT_MODE is defined,
since PenMount uses serial reporting mode and there is no
HID_DG_CONTACTCOUNT usage in it's report descriptor.
