Gianfar driver is now able to work without real phy subnode,
that is necessary to cope with fixed-link situation, when
SoC is connected to the Ethernet inteface or embedded switch
without any PHY. In this case, fixed-speed property will
describe such a situation for gianfar driver.
The property is in form duplexity speed
