ioport: Retire .generate_fdt_node functionality

The ioport routines support a special way of registering FDT node
generator functions. There is no reason to have this separate from the
already existing way via the device header.

Now that the only user of this special ioport variety has been
transferred, we can retire this code, to simplify ioport handling.
