[PATCH net-next 9/9] net: stmmac: rk: remove obsolete .set_*_speed() methods

[Russell King (Oracle)]

Now that no SoC implements the .set_*_speed() methods, we can get rid
of these methods and the now unused code in rk_set_clk_tx_rate().
Arrange for the function to return an error when the .set_speed()
method is not implemented.
