ptp_qoriq: fix register memory map
The 1588 timer on eTSEC Ethernet controller uses different register memory map with DPAA Ethernet controller. Now the new ENETC Ethernet controller uses same reigster memory map with DPAA. To support ENETC, let's use register memory map of DPAA/ENETC in default. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
