Baruch Siach 4e5ee86dcb gpio: mvebu: fix pwm .get_state period calculation 
commit e73b0101ae5124bf7cd3fb5d250302ad2f16a416 upstream.

The period is the sum of on and off values. That is, calculate period as

  ($on + $off) / clkrate

instead of

  $off / clkrate - $on / clkrate

that makes no sense.
