SoC-specific change of adding new pin functions into the platform dtsi
file shall be separated from the rest of the mezzanine board change,
send it as its own change, you may wish add all MCLK pins at once.

And the camera sensor reset "gpio" pin goes into the mezzanine specific
change.

Same as above.
