This device is identical to Techbite Arc 11.6, but ships with a different
DMI_PRODUCT_NAME ("ARC 11.6 128GB HD").
Without this DMI match, the Silead touchscreen reports an incorrect coordinate
range, resulting in partial and wrapped touch input under Wayland.
Reuse the existing techbite_arc_11_6_data for this model.
