enetc: add hardware timestamping support
This patch is to add hardware timestamping support for ENETC. On Rx, timestamping is enabled for all frames. On Tx, we only instruct the hardware to timestamp the frames marked accordingly by the stack. Because the RX BD ring dynamic allocation has not been supported and it is too expensive to use extended RX BDs if timestamping is not used, a Kconfig option is used to enable extended RX BDs in order to support hardware timestamping. This option will be removed once RX BD ring dynamic allocation is implemented.
