drm/i915/cnl: Add missing type case.
Paulo had noticed that inside cnl_ddi_vswing_program
the case was handling voltage but with no indication
of type where a missing type could also take us to that
path. So my first attempt was to add a message to
let clear who trigger that path.
However DK had a better idea that is to handle the
missed type sooner before it might take to that path.
So this v2 here uses his approach.
v2: Handle missed type sooner.
