Add support for tsunami with 64 processors and fix some console bugs

I steped on while doing it

console/console.c:
    Allocate more HWRPB pages so we have room for 64 percpu_rpbs
    Fix writing of Console Relocation Block virtual addresses so that
    if they are outside of the first page, which they will be with more
    than 8 processors, the correct adress is written
palcode/Makefile:
    Update makefile for tsunami with 64 processors
palcode/platform_m5.S:
    Add support for tsunami with 64 processors
