Revert "drm: bridge: mcde_dsi: Switch to devm_drm_of_get_bridge"
commit <3d7039e1e649> ("drm: bridge: mcde_dsi: Switch to devm_drm_of_get_bridge") switched to devm_drm_of_get_bridge for looking up if child node has panel or bridge.
However commit <b089c0a9b14c> ("Revert "drm: of: Lookup if child node has panel or bridge") has reverted panel or bridge child node lookup from devm_drm_of_get_bridge as it breaks the non-trivial cases the first child node might not be a panel or bridge.
So, revert this commit to switch the previous behavior of looking up child panel or bridge.
