This patch adds support for generic eDP sink through aux_bus. The eDP/DP controller driver should support aux transactions originating from the panel-edp driver and hence should be initialized and ready. The panel bridge supporting the panel should be ready before the bridge connector is initialized. The generic panel probe needs the controller resources to be enabled to support the aux transactions originating from the panel probe.
