btw., you missed to update a couple of places - pci/pci.h was used outside
of arch/x86 as well. Updated patch below.

Subject: [PATCH] x86, pci: move arch/x86/pci/pci.h to arch/x86/include/asm/pci_x86.h
Impact: cleanup
Now that arch/x86/pci/pci.h is used in a number of other places as well,
move the lowlevel x86 pci definitions into the architecture include files.
(not to be confused with the existing arch/x86/include/asm/pci.h file,
which provides public details about x86 PCI)
Tested on: X86_32_UP, X86_32_SMP and X86_64_SMP
