Register Ether device from bockw_init(), passing the platform data to it, adding only the RMII pin group to bockw_pinctrl_map[]. Although the LINK signal exists on the board, it's connected to the link/activity LED output of the PHY, thus the link disappears and reappears after each packet. We'd be better off ignoring such signal and getting the link state from the PHY indirectly.
