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!
Fixes: 65ce1f5834e9 ("drm/panel: ilitek-ili9882t: Switch Tianma TL121BVMS07 to DSC 120Hz mode")

Say Y if you want to enable support for panels based on the
Ilitek ILI9882t controller.

With that, I decided to apply to drm-misc-next. Please ask before and let me apply the changes, now the patch will be applied for v6.21... when asked, the drm-misc maintainers would prepare the drm- misc-next-fixes for use to apply. @maxime, thomas, what the right step now ?
