pwm: atmel: Fix calculation of prescale value
The prescale value used for calculating the period was incremented
afterwards, thus the resulting prescale value is by one too high.
This resulted in a PWM frequency only half as high as requested.
This patch moves the 64 bit division out of the prescale loop to
correct the above issue and make the calculation more efficient.
