[PATCH] PCI: clean up pci.h and split pci register info to separate header file.
This cleans up some of the #ifdef CONFIG_PCI stuff up, and moves the pci register info out to a separate file, where it belongs. Eventually we can stop including this file from within pci.h, but lots of code needs to be audited first. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
