2021-05-25pwm: visconti: Fix and simplify period calculationUwe Kleine-König1-10/+7
With the original code a request for period = 65536000 ns and period = 32768000 ns yields the same register settings (which results in 32768000 ns) because the value for pwmc0 was miscalculated. Also simplify using that fls(0) is 0.
