nb/intel/x4x: Don't use PCI operations on the pci_domain device
pci ops happen to work on this struct device since the device_path is an union.
This patch still keeps adding the fixed resources in the pci_domain
ops since moving it to the PCI ops which could properly use the
function argument for PCI operations would require all PCI IDs to be
added or else breakages are to be expected.
