TEST=pass FAFT test firmware_FwScreenPressPower

Original change's description:
> eve: Set VCCIO rail to 0.85 and disable low power
>
> 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.
