MN10300: Need pci_iomap() and __pci_ioport_map() defining

Include the generic definitions of pci_iomap() and __pci_ioport_map()
otherwise we can get errors like:

  lib/pci_iomap.c: In function 'pci_iomap':
  lib/pci_iomap.c:37: error: implicit declaration of function '__pci_ioport_map'
  lib/pci_iomap.c:37: warning: return makes pointer from integer without a cast

and:

  drivers/pci/quirks.c: In function 'disable_igfx_irq':
  drivers/pci/quirks.c:2893: error: implicit declaration of function 'pci_iomap'
  drivers/pci/quirks.c:2893: warning: initialization makes pointer from integer without a cast
  drivers/pci/quirks.c: In function 'reset_ivb_igd':
  drivers/pci/quirks.c:3133: warning: assignment makes pointer from integer without a cast
