[net-next 0/8] More MV88E6390 patches

[Andrew Lunn <andrew@lunn.ch>]

This is the ongoing work to add support for the Marvell 9390 family of
switches. There are now two MDIO busses, one for the internal PHYs and
an external bus for external PHYs. Add support for this external bus.

This switch supports 2Gbps, 2.5Gbps and 10Gbps ports. Add phy-modes
for these speeds/interfaces. These modes are then used to configure
ports 9 and 10, which support these speeds.

The internal PHYs oddly use a Marvell Vendor ID, but have empty
product ID. Trap reads of the product ID, and if it returns 0,
instead return the switch family ID. The Marvell PHY driver is then
extended to support this ID, treating the PHY as compatible with the
1540.

Both the internal and external MDIO busses are capable of clause 45
addressing, and is required to accessing the SERDES
interfaces. Implement support for clause 45.

And two fixes are included. There is no need to port these to stable,
the current support for the 6390 is not sufficient to be usable.
