  1. stm32/timer: avoid max_compare_value >= u16::MAX 

    With STM32 32 bits timers, the max_compare_value (AKA, ARR register)
can currently be set greater than u16::MAX, which leads to the following
assert!(max < u16::MAX as u32) in max_duty_cycle() when setting up a 1 kHz
SimplePwm on 84 MHz MCU.

The issue is fixed by forcing a max_compare_value that fits into 16 bits
when setting the frequency for a PWM.
