Add a HID_QUIRK_NO_INIT_REPORTS quirk for the Dell K12A keyboard-dock,
which can be used with various Dell Venue 11 models.

Without this quirk the keyboard/touchpad combo works fine when connected
at boot, but when hotplugged 9 out of 10 times it will not work properly.
Adding the quirk fixes this.
