We can't actually do any kind of sane job of configuring it otherwise. Also fix the comment about picking the "best" ECC mode. We can't do those any more; that relied on knowing what kind of CPU we're using (they don't all support 4-bit ECC), and current policy is that drivers not have cpu_is_*() checks.
