x86/amd_nb, EDAC: Rename amd_get_node_id()

This function doesn't give us the "Node ID" as the function name
suggests. Rather, it receives a PCI device as argument, checks
the available F3 PCI device IDs in the system and returns the
index of the matching Bus/Device IDs.

Rename it to amd_pci_dev_to_node_id().

No functional change is introduced.
