x86: fixup numa_node information for AMD CPU northbridge functions

Browse source

Currently the numa_node attribute for these PCI devices is 0 (it
corresponds to the numa_node for PCI bus 0). This is not a big issue
but incorrect.

This inconsistency can be fixed by reading the node number from CPU
NB function 0.

[ Impact: fill in dev->numa_node information, to optimize DMA allocations ]
