This does not yet enable access to domains other than 0, but updates the API to support domains. Places that use hard-coded bus/slot/function addresses have been updated to hardcode a domain of 0. A few places that have the PCI domain (segment) available such as the acpi_pcib_acpi.c Host-PCI bridge driver pass the PCI domain. The hpt27xx(4) and hptnr(4) drivers fail to attach to a device not on domain 0 since they provide APIs to their binary blobs that only permit bus/slot/function addressing. The x86 non-ACPI PCI bus drivers all hardcode a domain of 0 as they do not support multiple domains.
