kernel 2.6.38 introduced INPUT_PROP_DIRECT to indicate a device is
a direct touch (onscreen pointer) device. Use it so we do not
have to add individual devcies for that feature.
When INPUT_PROP_DIRECT was added, INPUT_PROP_MAX and EVIOCGPROP were
also defined. So, we only need to make sure INPUT_PROP_DIRECT is defined.
