This sets the pins to "gpio". Your earlier patch sets them to "mdio", so
removing this will break MDIO0 on the RB3011. It's likely that your
fixes for MDIO/QCA8K mean that the RB3011 can be switch to use the MDIO
driver rather than mdio-gpio, but that will need tested and this change
alone will definitely break things.
