Summary

HardwareTimer: pause() need to call HAL API to restore HAL state

Due to HAL Cube update (ex: for STM32L4 sha1 f41f10e)
it is now required to stop timer with HAL API
otherwise HAL state is not restored to HAL_TIM_STATE_READY,
and it is not possible to resume() a HardwareTimer after a pause().
Nevertheless it is not sufficient to guarantee that timer is stopped.
specially if some channels are still running.
So it is also necessary to keep also the call to LL_TIM_DisableCounter()

@ABOSTM ABOSTM force-pushed the HARDWARETIMER_PAUSE_RESTORE_STATE branch from 2a1ff77 to 9f15ada Compare September 9, 2020 11:52
