nb/amd/amdfam10: Work around sporadic lockups when CC6 enabled

The silicon in control of CC6 appears to contain minor bugs
    and / or deviations from the BKDG; through trial and error
    it was found that these issues can be worked around by reserving
    the entire possible CC6 save region, regardless of currently
    installed node count.
