Patch for aim/mp_cpudep.c that fixes slb-miss problem in cpudep_ap_bootstrap
for PPC970/PowerMacG5 contexts

No longer is aimslb.c involved.

More than the 970 might be appropriate for
similar changes, but as stands this is a PPC970
specific fix that makes the slbtrap/handle_kernel_slb_spill
code work in the cpudep_ap_bootstrap time frame.
It basically just moves initialization of HIOR, HID0,
and HID1 to earlier, before cpudep_ap_bootstrap
is called.

The patch was originally developed on head -r347003
without the patches from this bugzilla (or others
that I have in/from my investigations).
