device,nb/amd: Deduplicate add_more_links()
This function is duplicated in many AMD northbridge files, and all
the definitions have started to diverge somewhat. This moves a single
copy into device utils and deletes the rest. The function definition
from nb/amd/amdfam10 was chosen to be kept, since it contains several
fixes from commit 59d609217b (AMD fam10: Fix add_more_links) that
the others don't have.
For the ease of diffing, the checkpatch lints and other small cleanups
will be done in a follow-up patch.
