Uwe Kleine-König 1999e2c432 pwm: lp3943: Fix duty calculation in case period was clamped ...

[ Upstream commit 5e3b07ca5c ]

The hardware only supports periods <= 1.6 ms and if a bigger period is
requested it is clamped to 1.6 ms. In this case duty_cycle might be bigger
than 1.6 ms and then the duty cycle register is written with a value
bigger than LP3943_MAX_DUTY. So clamp duty_cycle accordingly.
