drm/panel: hx83121a: select DRM_DISPLAY_DSC_HELPER

Like a number of other panel drivers, this newly merged driver
needs DRM_DISPLAY_DSC_HELPER to be enabled:

arm-linux-gnueabi-ld: drivers/gpu/drm/panel/panel-himax-hx83121a.o: in function `himax_prepare':
panel-himax-hx83121a.c:(.text+0x1024): undefined reference to `drm_dsc_pps_payload_pack'
