Input: tsc200x-core - set INPUT_PROP_DIRECT
If INPUT_PROP_DIRECT is set, userspace doesn't have to fall back to old ways of identifying touchscreen devices. In order to identify a touchscreen device, Android for example, seems to already depend on INPUT_PROP_DIRECT to be present in drivers. udev still checks for either BTN_TOUCH or INPUT_PROP_DIRECT. Checking for BTN_TOUCH however can quite easily lead to false positives; it's a code that not only touchscreen device drivers use. According to the documentation, touchscreen drivers should have this property set and in order to make life easy for userspace, let's set it.
