This unconditionally overwrites any axis resolution calculated by touchscreen_parse_properties() from touchscreen-x-mm and touchscreen-y-mm device properties. Set the default resolution before calling touchscreen_parse_properties() so the default resolution remains in place when physical dimensions are omitted, while allowing touchscreen-x-mm and touchscreen-y-mm to override it when present.
