Set the VCCIO rail to 0.85V where it should be for Y-series parts instead of forcing it to 1.0V. The EDS is pretty clear that pushing this voltage higher on Y-series parts will have significant power penalty. (up to 250mW at 0.95V) We also don't want this rail dropping in low power mode, which shoudln't be happening as S0ix is disabled so SLP_S0 shouldn't assert, but just in case disable this as well.
