Add PC87392 support

This adds support for the NSC PC87392 Super I/O. It is used in Lenovo
Docking Stations as Super I/O chip.

v2 because of:

- skip some empty files
- missing newlines in Kconfig and Makefile.inc
- add the Kconfig option in sorted order

Thanks to idwer on irc for pointing that out.
