drm/imx: parallel-display: add DRM_DISPLAY_HELPER for DRM_IMX_PARALLEL_DISPLAY

When I build for an old imx53 platform I see the same as the test robot
saw before:

arm-buildroot-linux-gnueabihf-ld: drivers/gpu/drm/imx/ipuv3/parallel-display.o: in function `imx_pd_bind':
parallel-display.c:(.text+0xb8): undefined reference to `drm_bridge_connector_init'

Selecting DRM_DISPLAY_HELPER for DRM_IMX_PARALLEL_DISPLAY fixes the build.
