[PATCH 1/6] ppc/pegasos2: Restrict memory to 2 gigabytes |

The CHRP spec this board confirms to only allows 2 GiB of system
memory below 4 GiB as the high 2 GiB is allocated to IO and system
resources. To avoid problems with memory overlapping these areas
restrict RAM to 2 GiB similar to mac_newworld.
