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.
Fixes: 39135a305a0f ("drm/omap: displays: panel-dpi: Support for handling backlight devices")

Thanks, I've queued this for 4.14 fixes.
