Merge branch 'DPAA-PTP-clock-and-timestamping'

Yangbo Lu says:

====================
Support DPAA PTP clock and timestamping

This patchset is to support DPAA FMAN PTP clock and HW timestamping.
It had been verified on both ARM platform and PPC platform.
- The patch #1 to patch #5 are to support DPAA FMAN 1588 timer in
  ptp_qoriq driver.
- The patch #6 to patch #10 are to add HW timestamping support in
  DPAA ethernet driver.
