southbridge/cimx/sb900: Rename headers to match sb700 & sb800

Northbridge code includes these headers, so they all need to
have the same name to allow different combinations of northbridge
and southbridge. This changes the sb900 names to match sb700 & 
sb800, and points agesa/family12 and amd/torpedo to the new file 
names.
