This patch to implement Marvell PHY specific loopback callback function.
Verified working on Marvell 88E1510 at 1Gbps speed only. For 100Mbps and
10Mbps, found that the PHY loopback not able to function properly.
Possible due to limitation in Marvell 88E1510 PHY.

Tested on Intel Elkhart Lake platform (Synopsys Designware QoS MAC and
Marvell 88E1510 PHY).
