[ Upstream commit 499ec0ed5eb2f6a7fcaab2dd66ffc5993484bda9 ]
The new backlight code causes a link failure when backlight support itself is disabled:
drivers/gpu/drm/omapdrm/displays/panel-dpi.o: In function `panel_dpi_probe_of': panel-dpi.c:(.text+0x35c): undefined reference to `of_find_backlight_by_node'
This adds a Kconfig dependency like we have for the other OMAP display targets.
