Looks good, I was wondering if we can compute cpu_has_feature(CPU_FTR_ARCH_300) once for the instance
and use it, but I am just nit-picking. I've never tried using ASM_MMU_FTR_IF(), I don't know
if you've explored it. Not very important for this patchset though

So the design is that we allocate upto 2^24/16 entries for the partition table
and set the first entry LPID0 to use HPT with ps_field set to 0 and patb1
to be updated by the callback we provide via native_update_partition_table?
