Subject: [PATCH v2 1/4] hid-multitouch: change default mt_class

The safest quirk for a device (the one that works out of the box for
most of them) is MT_QUIRK_NOT_SEEN_MEANS_UP. Indeed, it does not
make any assumption on the device. When adding a new device, we can
easily test it against MT_CLS_DEFAULT, and then optimize it with other
quirks: that's why no device use MT_CLS_DEFAULT right now.
