Introduce architecture-specific "ptep_update_dirty_accessed()"
helper function to write-back the dirty and accessed bits from
ptep_establish().
Right now this defaults to the same old "set_pte()" that we've
always done, except for x86 where we now fix the (unlikely)
race in updating accessed bits and dropping a concurrent dirty
bit.
