HID: hid-multitouch: Switch to device groups
Switch the driver over to device group handling. By adding the HID_GROUP_MULTITOUCH group to hid-core, hid-generic will no longer match multitouch devices. By adding the HID_GROUP_MULTITOUCH entry to the device list, hid-multitouch will match all unknown multitouch devices, and udev will automatically load the module. Since HID_QUIRK_MULTITOUCH never gets set, the special quirks handling can be removed. Since all HID MT devices have HID_DG_CONTACTID, they can be removed from the hid_have_special_driver list. With this patch, the unknown device ids are no longer NULL, so the code is modified to check for the generic entry instead.
