Does Svadu without Svade mean that both menvcfg.ADUE or henvcfg.ADUE are
read-only 1 (the ISA is vague enough to permit this), or is it just an
awkward way to configure the default, so HS mode must assume that
henvcfg.ADUE=0 will be Svade?

Svade is mandatory in RVA profiles, so the corner-case case it not
anything I expect to see...
