Some PHYs have multiple software-selectable inputs and outputs,
including RGMII, SGMII, SerDes, etc.  New fields are added to the
"struct phy_device" for "port" and "transciever" to allow "ethtool" to
switch outputs at runtime.  The defaults for the new fields are
identical to the hardcoded values used previously.

This should make no functional changes to the PHY layer behavior, but
it will allow later PHY/ethernet drivers to override those fields.
