pwm: ab8500: Fix calculation of duty and period

After a check of the manual it becomes obvious that the calculations in
.apply() are totally bogus:

FreqPWMOutx was always written as zero, so the period was fixed at
3413333.33 ns. However state->period wasn't checked at all.
The lower 10 bits of duty_cycle were just used as DutyPWMOutx. So if
a duty cycle of 512 ns (or 1536 ns) was requested, it actually
programmed 1710000 ns. Other values were wrong by the same factor.
