msm: acpuclock-krait: Update HFPLL vdd_dig requirements for all SoCs

Updated hardware recommendations have been released. Capture these.
Although the voltage requirements are higher than was previously
specified, this is not expected to affect actual voltage levels
because the vdd_dig requirements of the of the L2 cache (as
enforced by acpuclock) are already higher than the new HFPLL
requirements.
