Log Message:
Add a common file to do pmap_zero_page/pmap_copy_page/pmap_pageidlezero and
pmap_syncicache.  This file uses a ppc feature in a sick and twisted way
to avoid mapping the physical pages used by those routines.  It performs
the operations with the MMU disabled but PPC exception save and retstore
the machine state and are invoked with the MMU disabled, this doesn't have
an adverse effect on the system.

Currently only enable for MPC6xx and !OLDPMAP.
