This device use another protocol while sending the events.
It's the same as the one described as "serial" by Microsoft.
We are keeping here the sn_move and sn_pressure parameters for
egalax devices.

Thanks for sending this patch.  If you like, you can add this for all
the patches except #2.  I'm not the best for reviewing sysfs code.

3-5 are nice cleanups to have.
