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.
