device/device_util: Rename dev_get_pci_domain

In coreboot, domain indicates hardware units that provide/group
resource windows, For Xeon-SP, domains are PCIe compatible and
further function in many aspects, e.g. PCIe, CXL, IOAT, UBOX.

Rename dev_get_pci_domain to dev_get_domain to align with coreboot
concept and distinguish from Xeon-SP concept.

TEST=Build and boot on intel/archercity CRB
