In line with the other controllers in the MSM driver, introduce a per-compatible list of base addresses which is used to resolve the "instance id" for the given DP controller. This instance id is used as index in the priv->dp[] array. Then extend the initialization code to initialize struct drm_encoder for each of the registered priv->dp[] and update the logic for finding a struct msm_dp from a struct drm_encoder. Lastly, bump the number of struct msm_dp instances carries by priv->dp to 3, the currently known maximum number of controllers found in a Qualcomm SoC.
