kbuild: automatically include northbridges

This change switches all northbridge vendors and southbridges
to be autoincluded by Makefile.inc, rather than having to be
mentioned explicitly in northbridge/Makefile.inc or in
northbridge/<vendor>/Makefile.inc.

This means, vendor and northbridge directories are now "drop
in", e.g. be placed in the coreboot directory hierarchy
without having to modify any higher level coreboot files.

The long term plan is to enable out of tree components to be
built with a given coreboot version (given that the API did not
change).
