video: exynos: fix modular build
The s6e8ax0 driver has a dependency on BACKLIGHT_CLASS_DEVICE, which can be configured as a loadable module, so we have to make the driver a tristate symbol as well, to avoid this error: drivers/built-in.o: In function `s6e8ax0_probe': :(.text+0x23a48): undefined reference to `devm_backlight_device_register' This also means we get another error from a missing export, which this fixes as well: ERROR: "exynos_mipi_dsi_register_lcd_driver" [drivers/video/fbdev/exynos/s6e8ax0.ko] undefined! The drivers are all written to be loadable modules already, except the Kconfig options for that are missing, which makes the patch really easy. Finally, the EXYNOS_VIDEO option is turned into tristate as well for good measure, as all framebuffer drivers should be configurable as modules, though this change is not strictly necessary.
