This change enables the use of SW timestamping on the Raspberry Pi 4. bcmgenet's transmit function bcmgenet_xmit() implements software timestamping. However the SOF_TIMESTAMPING_TX_SOFTWARE capability was missing and only SOF_TIMESTAMPING_RX_SOFTWARE was announced. By using ethtool_ops bcmgenet_ethtool_ops() as get_ts_info(), the SOF_TIMESTAMPING_TX_SOFTWARE capability is announced.
