powerpc/8xx: Use SCRATCH0 and SCRATCH1 also for TLB handlers SCRATCH0 and SCRATCH1 are only used in Exceptions prologs where no other exception can happen. There is therefore no need to preserve them accross TLB handlers, we can use them there as in other exceptions. One of the advantages is that they do not suffer CPU6 errata unlike M_TW register.
