Make pmap_copy_page() L2-cache friendly by doing the copy through the
cacheable window on physical memory (KSEG0). On the Sibyte processor
going through the uncacheable window (KSEG1) bypasses both L1 and L2
caches so we may end up with stale contents in the L2 cache.

This also makes it consistent with the rest of the function that
uses cacheable mappings to copy pages.
