Subject: [PATCH] floppy: Provide a PNP device table in the module.

The missing device table means that the floppy module is not
auto-loaded, even when the appropriate PNP device (0700) is found.

We don't actually use the table in the module, since the device doesn't
have a struct pnp_driver, but it's sufficient to cause an alias in the
module that udev/modprobe will use.
