Those tests check: - the ability for a phy-user to get a phy based on its name or its index - the ability of a phy device (provider) to manage multiple ports - the ability to perform operations on the phy (init,deinit,on,off) - the behavior of the uclass when optional operations are not implemented

changes since v3: updated the tests to reflect the changes in the PHY framework : * use several phy devices (provider) * use several phy ports per phy device
