net: ethernet: cortina: Implement .set_pauseparam() 



The Cortina Gemini ethernet can very well set up TX or RX
pausing, so add this functionality to the driver in a
.set_pauseparam() callback. Essentially just call down to
phylib and let phylib deal with this, .adjust_link()
will respect the setting from phylib.
