typedef DECLCALLBACK ( int   ) 

Callback function for mapping an PCI I/O region.

Returns:
VBox status code.
Parameters:
pPciDev Pointer to PCI device. Use pPciDev->pDevIns to get the device instance.
iRegion The region number.
GCPhysAddress Physical address of the region. If enmType is PCI_ADDRESS_SPACE_IO, this is an I/O port, otherwise it's a physical address.
NIL_RTGCPHYS indicates that a MMIO2 mapping is about to be unmapped and that the device deregister access handlers for it and update its internal state to reflect this.

Parameters:
enmType One of the PCI_ADDRESS_SPACE_* values.
Remarks:
The address is *NOT* relative to pci_mem_base.

Todo:
r=bird: We should just drop all these items, restoring doesn't make sense.
