I'm also changing "md_mitigation" to "mdd_mitigation" and standardizing
on "md_" and "MDD_" prefixes. If we are to "enable" mitigations rather
than disabling features, then let's make sure that's what we're always
referring to it in that manner. Otherwise it's confusing to see "MD_ON"
meaning that MDD is set and we are actually not enabling MD. So I change
that to "MDD_ON", etc.
