[U-Boot] [PATCH v2 3/4] dm: net: macb: Implement link speed change callback

At present the link speed change callback is a nop. According to macb device tree bindings, an optional "tx_clk" is used to clock the ethernet controller's TX_CLK under different link speed. In 10/100 MII mode, transmit logic must be clocked from a free running clock generated by the external PHY.
