mvebu: puzzle-m902: add driver for MCU driving LEDs, fan and buzzer
Backport MFD driver for communicating with the on-board MCU found on IEI World Puzzle appliances. Improve the driver to support multiple LEDs, apply a default state and let MCU take care of blinking if timing is within supported range. Wire up LEDs and fan for Puzzle M902 in device tree.
