drm/i915/dp: Factor out helper to get link rate capabilities

Factor out a helper to get the supported link rates. This allows to
gather all the link capabilities and pass these to the link capability
module from a single place. A follow-up change will extend this to
gather and pass the maximum lane count capability in the same way.
