At the moment, the struct pci_filp_private does not have any other users
outside of the drivers/pci/proc.c file, and additionally its also only
ever used (alongside all of its users) when the macro HAVE_PCI_MMAP is
set.
Thus, enclose struct pci_filp_private in an preprocessor condition so
that it's only declared when the HAVE_PCI_MMAP macro is set, which
otherwise would be unused should the macro hasn't been set.
