drm/i915: simplify DP/DDI port width macros
If we ever leak a non-DP compliant port width through here, we have a
pretty serious issue. So just rip out all these WARNs - if we need
them it's probably better to have them at a central place where we
compute the dp lane count.
Also use the new DDI width macro for FDI mode.
