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)
