board: imx53: Always disable display before starting kernel
This patch prevents from the situation where we may end up with garbage displayed on the LCD panel. Such situation occurs when one performs "reboot -f" in Linux and then stop in U-boot (or observe the garbage on the screen during boot up). To prevent from such situation - the PWM pin is configured as GPIO and set to LOW. Signed-off-by: Lukasz Majewski <lukma@denx.de>
