prism54: add ethtool -i interface

Add support for "ethtool -i" to prism54 driver.

ethtool -i queries the specified device for associated driver information.

This helps tools like Fedora's system-config-network to provide GUI management of network devices. I learned how to write this patch by reading the ipw2100 driver code.
