PCI: Add 'nodomains' boot option, and pci_domains_supported global
* Introduce pci_domains_supported global, hardcoded to zero if !CONFIG_PCI_DOMAINS. * Introduce 'nodomains' boot option, which clears pci_domains_supported on platforms that enable it by default (x86, x86-64, and others when they are converted to use this).
