northbridge/amdfam10: Deal with PCI_ADDR() better 

PCI_ADDR() is tightly coupled with different setup_resource_map()
variants so move the declaration away from global namespace.

In the implementation of setup_resource_map() use the bottom
12 bits as the register mask like the other variants do already.
