This is a direct commit to stable/14 to preserve the ABI of the the pci_cfgregread and pci_cfgregwrite functions. The new routines are renamed to add a _domain suffix and macros map the new API to the new functions. Note: No API compatibility has been provided as modules in ports should not be using this internal API (normal PCI drivers use pci_read_config and pci_write_config with a device_t).
