drm/imx: imx-tve: use drm managed resources
Use drmm_simple_encoder_alloc() to align encoder memory lifetime with the drm device. drm_encoder_cleanup() is called automatically before the memory is freed. Also fold imx_tve_register() into imx_tve_bind(). Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch>
