Add tilcdc_crtc_atomic_check(). Checks the display mode validity and the presence of the mandatory primary plane. The drm_crtc_helper_funcs mode_fixup() callback is left untouched and the check function does no try to do its job on purpose, despite what the mode_fixup() callback's documentations suggests. The plane's check() callback needs to set drm_crtc_state's ->mode_changed to true if the pixel format for the framebuffer changes. Because of this drm_mode_config_funcs atomic_check() callback needs to call drm_atomic_helper_check_modeset() once more after it has called drm_atomic_helper_check_planes(). If the fixing of the adjusted_mode would be done in drm_crtc_helper_funcs atomic_check() callback, it would get over written by the extra drm_atomic_helper_check_modeset() call.
