drm/i915: WARN if a port should use VBT provided vswing tables

Browse source

We don't parse the VBT vswing/preemphassis tables at all currently.
Let's WARN if a port wants to use them so we get a heads up that
whether we really need to implement this stuff or not. My
current stash contains no VBTs with this bit set.

v2: Move to print_ddi_port() (Jani)
