Subject: [PATCH] drm/imx: parallel-display: select DRM_IMX_LEGACY_BRIDGE

Add the missing select DRM_IMX_LEGACY_BRIDGE to fix kernels builds that
have the i.MX parallel-display driver enabled, but the LVDS display
bridge driver disabled.

Fixes build errors like:

  ld: vmlinux.o: in function `imx_pd_probe':
  parallel-display.c:(.text+0x3129db): undefined reference to `devm_imx_drm_legacy_bridge'

Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202409060118.z8BxMg7Z-lkp@intel.com/
Fixes: f94b9707a1c9 ("drm/imx: parallel-display: switch to imx_legacy_bridge / drm_bridge_connector")
