pin_duration is converted from the user-provided period to SJA1105
clock ticks and is later passed as the cycle_time argument to

Very small period values may become zero after the conversion,
which can lead to a division by zero in future_base_time().

Reject zero pin_duration values and values that exceed the
supported range.

Which is better, reject, or round up to 1?
