ea33a5def5 mvebu: puzzle: fix fan thermal cooling driver 
Several fixes for the Puzzle WT61P803 hwmon driver were needed to make
it behave well as thermal cooling device:
 - wire-up cooling device with OF node in device tree
 - properly parse cooling-levels (u32 with range check vs. u8)
 - actually use cooling-levels
 - keep current state and only write to uC if state has changed
   (avoids flooding the uC with commands which will result in uC crashing)

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.
