drm/panel: Fix build error when CONFIG_DRM_PANEL_SAMSUNG_ATNA33XC20=y && CONFIG_DRM_DISPLAY_HELPER=m
[ Upstream commit a67664860f7833015a683ea295f7c79ac2901332 ]
If CONFIG_DRM_PANEL_SAMSUNG_ATNA33XC20=y && CONFIG_DRM_DISPLAY_HELPER=m,
bulding fails:
drivers/gpu/drm/panel/panel-samsung-atna33xc20.o: In function `atana33xc20_probe':
panel-samsung-atna33xc20.c:(.text+0x744): undefined reference to
`drm_panel_dp_aux_backlight'
make: *** [vmlinux] Error 1
Let CONFIG_DRM_PANEL_SAMSUNG_ATNA33XC20 select DRM_DISPLAY_DP_HELPER and
CONFIG_DRM_DISPLAY_HELPER to fix this error.
