Based on the removal of the g_dp_display and the movement of the priv->dp lookup into the DP code it's now possible to have multiple DP instances.
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 associating each struct msm_dp with the struct dpu_encoder_virt.
A new enum is introduced to document the connection between the instances referenced in the dpu_intf_cfg array and the controllers in the DP driver and sc7180 is updated.
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.
