PCI: X86: Introduce and enable PCI domain support
* fix bug in pci_read() and pci_write() which prevented PCI domain
support from working (hardcoded domain 0).
* unconditionally enable CONFIG_PCI_DOMAINS
* implement pci_domain_nr() and pci_proc_domain(), as required of
all arches when CONFIG_PCI_DOMAINS is enabled.
* store domain in struct pci_sysdata, as assigned by ACPI
* support "pci=nodomains"
