Fabrice Gasnier 0a56eabc4e iio: trigger: stm32-timer: preset shouldn't be buffered 
Currently, setting preset value (ARR) will update directly 'Auto reload
value' only on 1st write access. But then, ARPE is set. This makes
ARR a shadow register. Preset value should be updated upon each
write request: ensure ARPE is 0. This fixes successive writes to
preset attribute.
