Ralink SoC uses the same 8250 iotype as AU1x00. In order to make this work form a devicetree, the correct iotype needs to be probed inside of_platform_serial_setup(). Ralink SoC has a different iosize than AU1x00, which causes serial8250_port_size() to return 0x1000 instead of the correct 0x100. Instead of adding another static if statement we probe the real iosize from the resource inside the devicetree.
