ENGR00151310 mx53 smd: remove GPIO_9 pull down
This patch is used to remove the workaround "pull down GPIO_9" to support reboot in mx53 SMD. Another workaround is adopted into U-Boot to force warm reset as cold reset. New workaround can support watchdog timeout in mx53 SMD board. Signed-off-by: Lily Zhang <r58066@freescale.com>
