That sounds like the constraints are wrong actually, if 0.86V can only
be used during system suspend then it shouldn't be in the valid voltage
range - the suspend voltage doesn't need to be in the range used during
normal operation.  If we might use it during runtime suspend then it
does need to be there though.
