Input: aiptek - do not try to export associated event device
Do not try to export via sysfs associated event device - it does not
work when evdev is a module that is loaded after aiptek; also it pokes
too deply into input core internals.
Userspace should rely on udev to set up permanent device name for
the tablet.
