input: cyapa: re-architecture driver to support multi-trackpads in one driver

In order to support two different communication protocol based trackpad device in one cyapa, the new cyapa driver is re-designed with one cyapa driver core and two devices' functions component. The cyapa driver core is contained in this patch, it supplies the basic function with input and kernel system and also defined the interfaces that the devices' functions component needs to apply and support. Also, in order to speed up the system boot time, the device states detecting and probing process is put into the async thread. TEST=test on Chromebooks.
