After commit a208ffd251d0 ("of: Enable console on serial ports
specified by /chosen/stdout-path") the kernel is able to know what
serial console to use if the DT defined an stdout-path property so
should be preferred instead of using a console= parameter.
I'll post today a series to change that on all exynos5 boards so you
can base on that.

I think this should be defined in exynos5410.dtsi instead since is an
IP block in the SoC and referenced in the .dts using a label to change
the clock-frequency in the board.
