PCI: Declare pci_filp_private only when HAVE_PCI_MMAP
The struct pci_filp_private has no users outside drivers/pci/proc.c and is
only used when HAVE_PCI_MMAP is defined.
Wrap the struct pci_filp_private definition itself in #ifdef HAVE_PCI_MMAP.
Found by cppcheck:
$ cppcheck --enable=all --force drivers/pci/proc.c
drivers/pci/proc.c:192:6: style: struct member 'pci_filp_private::write_combine' is never used. [unusedStructMember]
