drm/i915/dp: rename rate_to_index() to intel_dp_rate_index() and reuse 

Rename the function, move it at the top, and reuse in
intel_dp_link_rate_index(). If there was a reason in the past to use
reverse search order here, there isn't now.

The names may be slightly confusing now, but intel_dp_link_rate_index()
will go away in follow-up patches.

v2: Use name intel_dp_rate_index (Dhinakaran)
