Subject: [PATCH] drm: panel: visionox: add backlight dependency

From: Arnd Bergmann <arnd@...db.de>

The newly added driver uses the backlight subsystem but is missing the
corresponding Kconfig dependency:

arm-linux-gnueabi-ld: drivers/gpu/drm/panel/panel-visionox-vtdr6130.o: in function `visionox_vtdr6130_probe':
panel-visionox-vtdr6130.c:(.text+0xdee): undefined reference to `devm_backlight_device_register'

Fixes: 65dc9360f741 ("drm: panel: Add Himax HX8394 panel controller driver")
Signed-off-by: Arnd Bergmann <arnd@...db.de>
