Nick Bowler 56277f40d7 phylib: mdio: Add sysfs attribute for PHY identifiers. ...

This adds a phy_id sysfs attribute to MDIO devices, containing the
32-bit PHY identifier reported by the device.  This attribute can
be useful when debugging problems related to phy drivers.  Other
enumerable buses already have similar attributes.
