drm/i915/cnl: Fix DP max rate for Cannonlake with port F.

Browse source

On CNL SKUs that uses port F,  max DP rate is 8.1G for all
ports when we have the elevated voltage (higher than 0.85V).

v2: Make commit message more generic.
v3: Move conditions to a helper to get easier to read. (Ville).
v4: Add a mention to the numerical voltage on commit
    message per Manasi request.
v5: Thanks CI! "error: control reaches end of non-void function"
