heaters: Change default smooth_time from 2 seconds to 1 second
A larger smooth_time results in a slower reaction time for the PID.
This increased delay can cause temperature oscillations with high
power heaters. Many boards produce good results without any
smoothing. So, it seems a smooth_time of 1 second is a better
default.
