PCI/portdrv: Move private things to portdrv.c

Previously several things used by portdrv_core.c and portdrv_pci.c were
shared by defining them in portdrv.h.  Now that portdrv_core.c and
portdrv_pci.c have been squashed, move things that can be private into
portdrv.c.  No functional change intended.
