drm: imx: remove struct imx_drm_crtc and imx_drm_crtc_helper_funcs
With the vblank hooks in struct drm_crtc_funcs, we do not need to maintain the CRTC specific vblank callbacks with struct imx_drm_crtc_helper_funcs any more. By moving the stuff that we currently do in imx_drm_add_crtc(), like of_node setting and drm_crtc_helper_add()/drm_crtc_init_with_planes() invoking, we can kill things like struct imx_drm_crtc, imx_drm_crtc_helper_funcs and related functions completely. Functions ipu_enable_vblank() and ipu_disable_vblank() are moved around without changes, only for saving the forward declarations.
