imx-drm: initialise drm components directly 

Now that our bind function is only ever called during the main DRM
driver ->load callback, we don't need to have the imx_drm_connector or
imx_drm_encoder abstractions anymore.  So let's get rid of it, and move
the DRM connector and encoder setup into the connector support files.
