drm/modes: add non-OF stub for of_get_drm_display_mode 

If CONFIG_OF is disabled, of_get_drm_display_mode is not compiled in,
and drivers using it fail to build:

  ld: drivers/gpu/drm/imx/parallel-display.o: in function `imx_pd_connector_get_modes':
  parallel-display.c:(.text+0x8d): undefined reference to `of_get_drm_display_mode'

Add an inline stub so they can be build-tested with non-OF
configurations.
