drm/panel: nt37801: select CONFIG_DRM_DISPLAY_DSC_HELPER

The newly added driver uses the DSC helper module, but does not
select its Kconfig symbol, so configurations are possible that
cause a link failure:

ERROR: modpost: "drm_dsc_pps_payload_pack" [drivers/gpu/drm/panel/panel-novatek-nt37801.ko] undefined!
