CHROMIUM: exynos: dts: configure audio codec master clock pin

On Spring, the I2S0 clock is connected to MCLK2/GPIO3 instead of MCLK1.

Explicitly configure the pin on boards I have tested and let the sane
default value (MCLK1 as before) for others.

play sound on Snow with the codec on MCLK1, on Spring proto-1 with the
codec on MCLK2.
