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

[Anton Vorontsov]

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).
