Log: 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.
