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.
