ARM: S3C24XX: Free the backlight gpio requested in Mini2440 board code
The backlight gpio must not be left requested in the board code, otherwise s3c24xx_led driver can't successfully claim it. So request the backlight gpio, configure it to proper state and gpio_free right away. This change is required for converting the s3c24xx_led driver to the gpiolib API.
