Merge branch 'amd-xgbe-add-hardware-ptp-timestamping'

Raju Rangoju says:

====================
amd-xgbe: add hardware PTP timestamping

Remove the hwptp abstraction and associated callbacks from the
struct xgbe_hw_if {} and move them to separate file after cleanup.

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