net: thunderx: add timestamping support
This adds timestamping support for both receive and transmit
paths. On the receive side no filters are supported i.e either
all pkts will get a timestamp appended infront of the packet or none.
On the transmit side HW doesn't support timestamp insertion but
only generates a separate CQE with transmitted packet's timestamp.
Also HW supports only one packet at a time for timestamping on the
transmit side.
