[net v1] net: stmmac: set IC bit when transmitting frames with HW timestamp

From: Roland Hii When transmitting certain PTP frames, e.g. SYNC and DELAY_REQ, the PTP daemon, e.g. ptp4l, is polling the driver for the frame transmit hardware timestamp. The polling will most likely timeout if the tx coalesce is enabled due to the Interrupt-on-Completion (IC) bit is not set in
