drm/panel: ilitek-ili9882t: Select DRM_DISPLAY_DSC_HELPER

The panel-ilitek-ili9882t driver uses drm_dsc_pps_payload_pack() which
is provided by the DRM_DISPLAY_DSC_HELPER. Add the missing Kconfig
select to fix the following build error:

  ERROR: modpost: "drm_dsc_pps_payload_pack" [drivers/gpu/drm/panel/panel-ilitek-ili9882t.ko] undefined!
