Aleksandrova Alyona aee5836273 net: dsa: sja1105: round up PTP perout pin duration 
pin_duration is converted from the user-provided period to SJA1105
clock ticks and is later passed as the cycle_time argument to
future_base_time().

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

Round zero pin_duration up to 1 tick so that the smallest unsupported
periods use the minimum non-zero hardware duration instead of passing
zero to future_base_time().

Fixes: 747e5eb31d ("net: dsa: sja1105: configure the PTP_CLK pin as EXT_TS or PER_OUT")
