POWER7 inherited this from the other 64bit cores. Does any of those actually
implement MMUCFG? It's definitely category E in the 2.04 ISA already.
Please check all supported CPU types' book iv's and remove MMUCFG (and maybe
other SPRs if you can spot them) if it's not really implemented on hardware.
