[PATCH] ARM: imx_v6_v7_defconfig: Restore CONFIG_BACKLIGHT_CLASS_DEVICE

[PATCH] ARM: imx_v6_v7_defconfig: Restore CONFIG_BACKLIGHT_CLASS_DEVICE

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

Since commit bfac19e239a7 ("fbdev: mx3fb: Remove the driver") backlight
is no longer functional.

The fbdev mx3fb driver used to automatically select 
CONFIG_BACKLIGHT_CLASS_DEVICE.

Now that the mx3fb driver has been removed, enable the
CONFIG_BACKLIGHT_CLASS_DEVICE option so that backlight can still work
by default.

Tested on a imx6dl-sabresd board.

Fixes: bfac19e239a7 ("fbdev: mx3fb: Remove the driver")
