[PATCH 2/2] powerpc/83xx: add support for MCU on 8349emitx, 837xrdb and 8315erdb boards

MCU is an external Freescale MC9S08QG8 microcontroller, mainly used to
provide soft power-off function, but also exports two GPIOs (wired to
the LEDs and also available from the external headers).

Kumar, I think you merged this patch incorrectly ...

This node is supposed to go under the I2C node, but you put it under
the DMA node.

I've noticed this on the other 'stg pull', when it told me that the
patch isn't empty (stg patch becomes empty if merged).

This should be fixed already:

Anyway, thanks for heads up!
