Adds complete support for hardware-based PTP (IEEE 1588)
timestamping to the AMD XGBE driver.

- Initialize and configure the MAC PTP registers based on link
  speed and reference clock.
- Support both 50MHz and 125MHz PTP reference clocks.
- Update the driver interface and version data to support PTP
  clock frequency selection.
