northbridge/amd/amdfam10: Unify CBMEM location across UMA and non-UMA
The CBMEM memory segment is always placed at TOM - UMASIZE when GFXUMA
is enabled, however when GFXUMA is disabled an attempt was made to locate
the CBMEM memory segment above the I/O hole in certain rare cases.
Removing this special case does not impact functionality, and paves
the way for early CBMEM support.
