powerpc: Fix bogus cache flushing on all 40x and BookE processors v2

We were missing the CPU_FTR_NOEXECUTE bit in our cputable for all
these processors. The result is that update_mmu_cache() would flush
the cache for all pages mapped to userspace which is totally
unnecessary on those processors since we already handle flushing
on execute in the page fault path.

This should provide a nice speed up ;-)
