[v2] ptp_qoriq: add initialization message

[Yangbo Lu <yangbo.lu@nxp.com>]

Current ptp_qoriq driver prints only warning or error messages.
It may be loaded successfully without any messages.
Although this is fine, it would be convenient to have an oneline
initialization log showing success and PTP clock index.
The goods are,
- The ptp_qoriq driver users may know whether this driver is loaded
  successfully, or not, or not loaded from the booting log.
- The ptp_qoriq driver users don't have to install an ethtool to
  check the PTP clock index for using. Or don't have to check which
  /sys/class/ptp/ptpX is PTP QorIQ clock.
