af0e70ec17 [mdio] Add MDIO support for "extended" registers as defined by IEEE 802.3 Clause 45.
IEEE 802.3 Clause 45 added backwards-compatible support for 2^16 PHY registers
through the addition of an additional device address frame.

Clause 45 addressing is used in 10Gbe PHYs, 802.3az EEE registers, etc. It may
make sense to provide a similar extension to the miibus interface, but I've
refrained from unilaterally doing so here.

86c6170821 [mdio] migrate mdiobus out of etherswitch and into a top-level device of its own.
The mdio driver interface is generally useful for devices that require
MDIO without the full MII bus interface. This lifts the driver/interface
out of etherswitch(4), and adds a mdio(4) man page.
