drm/i915/ehl: Update port clock voltage level requirements
Voltage level depends not only on the cdclk, but also on the DDI clock.
Last time the bspec voltage level table for EHL was updated, we only
updated the cdclk requirements, but forgot to account for the new port
clock criteria.
Bspec: 21809
