[Intel-gfx] [PATCH 09/12] drm/i915: Remove useless rate_to_index() usage

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

No need to iterate the rates array in intel_dp_max_link_rate(). We know
the max rate will be the last entry, and we already know the size.
