drm/udl: Init connector before encoder and CRTC
To mimic simple-pipe, we initialize the connector before the rest of the display pipeline. v2: * remove unnecessary calls to drm_connector_{register,unregister}() Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Emil Velikov <emil.l.velikov@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191210084905.5570-2-tzimmermann@suse.de
