Merge branch 'phy-c45-loopback'

Wong Vee Khee says:

====================
Add support for Clause-45 PHY Loopback

This patch series add support for Clause-45 PHY loopback.

It involves adding a generic API in the PHY framework, which can be
accessed by all C45 PHY drivers using the .set_loopback callback.

Also, enable PHY loopback for the Marvell 88x3310/88x2110 driver.
