[LinuxBIOS] [PATCH] v3: Refactoring, northbridgelib.c

[Uwe Hermann]

See patch.

Factor out common code. In v2 98% of all northbridges do exactly the
same thing (in these functions), thus refactor. It's easy to override
the common functions if a northbridge needs slightly different ones
(I think K8 will, for example).

Uwe.
