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.

STM32 SimplePwm: Fix regression and re-enable output pin

PR #2499 implemented timer hierarchy, but removed enable_outputs()
from trait CaptureCompare16bitInstance and from SimplePwm.
This functions is required for advanced timers to set bit BDTR.MOE
and to enable the output signal.

stm32: allow setting PWM duty cycle to 100%
...
Setting the compare_value to max_compare_value make the PWM output
go low when the timer reach the max_compare_value and go high again
on the next timer clock, when the value roll back to 0.
So to allow a 100% PWM that never goes low, the compare_value must
be set to max_compare_value + 1.
