[PATCH] drm/panel: hx83121a: select DRM_DISPLAY_DSC_HELPER

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

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'

Fixes: a7c61963b727 ("drm/panel: Add Himax HX83121A panel driver")
