Jean-Jacques Hiblot 3b63db37ad phy: add a NO-OP phy driver
This driver is used to stub PHY operations in a driver (USB, SATA).
This is useful when the 'client' driver (USB, SATA, ...) uses the PHY
framework and there is no actual PHY harwdare to drive.

PHY support.
This framework is designed to provide a generic interface for PHY
devices. PHY devices are dedicated hardware that handle the physical
layer of the protocols in the OSI model.
PHYs are commonly used for high speed interfaces such as Serial-ATA
or PCI express.
The API provides functions to initialize/deinitialize the
PHY, power on/off the PHY, and reset the PHY. It's meant to be as
compatible as possible with the equivalent framework found in the
linux kernel.

This select a dummy sandbox PHY driver. It used only to implement
the unit tests for the phy framework

Support for a no-op PHY driver (stubbed PHY driver).
This is useful when a driver uses the PHY framework but no real PHY
