Add PC87382 support

This patch adds support for NSC PC87382 Super I/O. It is used in many
Lenovo Notebooks as Docking LPC Switch.

v2 because of:

- Skip some empty files
- Fix newlines in Kconfig and Makefile.inc
- chip.h missed uart8250.h include
- add the Kconfig option in sorted order

Thanks to idwer on irc for pointing that out.
