Because it isn't really a northbridge. In an Intel system the 
northbridge contains the memory controller. So MC init code is in the 
northbridge directory. On AMD processors, the northbridge is integrated 
on in the CPU so you see CPU directories under the northbridge 
directory. The southbridge directory is used for chipsets like the 
K8T890 Hyptertransport tunnel with a PCIe bridge. Other examples of this 
are the AMD 8111/8131 and Broadcom 5780/5785.

Maybe we should consider renaming the directories to be more clear.
northbridge -> memorycontroller
southbridge -> chipsets

No idea, can you bump that patch thread?
