Merge branch 'module_phy_driver'

Johan Hovold says:

====================
net: phy: add module_phy_driver macro

Add module_phy_driver macro that can be used by PHY drivers that only
calls phy_driver_register or phy_drivers_register (and the corresponding
unregister functions) in their module init (and exit).

This allows us to eliminate a lot of boilerplate code.

Split in three patches (actual macro and two driver change classes) in
order to facilitate review.
