phy: power management support
This patch adds the power management support into the physical
abstraction layer.
Suspend and resume functions respectively turns on/off the bit 11
into the PHY Basic mode control register.
Generic PHY device starts supporting PM.
In order to support the wake-on LAN and avoid to put in power down
the PHY device, the MDIO is aware of what the Ethernet device wants to do.
Voluntary, no CONFIG_PM defines were added into the sources.
Also generic suspend/resume functions are exported to allow
other drivers use them (such as genphy_config_aneg etc.).
Within the phy_driver_register function, we need to remove the
memset. It overrides the device driver owner and it is not good.
