drm/i915: Fix ICL MG PHY vswing handling
commit a2a5f562 upstream. The MH PHY vswing table does have all the entries these days. Get rid of the old hacks in the code which claim otherwise. This hack was totally bogus anyway. The correct way to handle the lack of those two entries would have been to declare our max vswing and pre-emph to both be level 2.
