[parisc-linux] Turn off CONFIG_PCI

[Matthew Wilcox <willy@ldl.fc.hp.com>]

A number of people have been asking for the ability to turn off CONFIG_PCI,
and while I was reviewing the outstanding diff vs 2.4.9, I noticed I could
take out some of the patch if I just made some slight alterations.  Please
test this patch; it compiles for me.
