net: stmmac: add fix_mac_speed support for socfpga
This patch adds fix_mac_speed() support for Altera socfpga Ethernet controller. Emac splitter is a soft IP core in FPGA system that converts GMII interface from Synopsys mac to RGMII/SGMII interface. This splitter core is an optional IP if user would like to use RGMII/SGMII interface in their system. Software needs to update a register in splitter core when there is speed change.
