drm/bridge: Refactor out the panel wrapper from the lvds-encoder bridge.
Many DRM drivers have common code to make a stub connector implementation that wraps a drm_panel. By wrapping the panel in a DRM bridge, all of the connector code (including calls during encoder enable/disable) goes away. v2: Fix build with CONFIG_DRM=m, drop "dev" argument that should just be the panel's dev, move kerneldoc up a level and document _remove(). v3: Fix another breakage with CONFIG_DRM=m, fix breakage with CONFIG_OF=n, move protos under CONFIG_DRM_PANEL_BRIDGE, wrap a line.
