[U-Boot] [PATCH 2/2] EXYNOS5: Enable console multiplexing in u-boot when LCD support is enabled

[Ajay Kumar]

With this patch, stdout/stderr is assigned to serial and also to LCD.
Initially, u-boot output console is observed via serial port.
If you also have a DP panel connected onto your SMDK5250 board,
you can switch to LCD console by typing "setenv stdout lcd".
You can always switch back to serial using "setenv stdout serial".
You can switch error console(stderr) as well, using similar commands.
