[PATCH 2.6.19.1] prism54: add ethtool -i interface

[Kai Engert <kengert@redhat.com>]

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.
