The Cortina PHY on T2080RDB and T4240RDB requires the use of the
dedicated Cortina PHY driver. This patch series enables it for
DPAA platforms and uses it on T4240RDB and T2080RDB.

Cortina PHYs are present on T4240RDB and T2080RDB. Enable the driver
by default.

The Cortina PHY requires the use of the dedicated Cortina PHY driver
instead of the generic one.

Applied with the changelog updated to talk about hardware compatibility
("The Cortina PHY is not compatible with IEEE 802.3 clause 45") rather
than driver choice.
