[wireless atmel] various updates

Below is a patch against 2.6.1-rc1 which has that fix and
quite a few other components. viz:

* Bumped version to 0.9

* Dmitry Torokhov's skb-leak and netif_carrier patches.

* Added a couple of fields to /proc/driver/atmel

* Fixed failure to call unregister_netdev in a couple of error-unwind
  paths. I think this fixes the 
  unregister_netdevice: waiting for eth1 to become free.
  bugs, but I don't have definative proof.

* Remove floating-point constants just in case the compiler doesn't.

* Fixed bug in scanning.

* Added firmware versioning, driver will search through different
  available versions of firmware 'till it finds an available one.

* Changed firmware URL in configure help to a directory rather than a
  file, so I can release new named versions.

* Added support for later releases of the firmware, which are WPA aware.
  Firmware verion is automatically detected, so users who upgrade their
  kernel but not their firmware won't have problems.


The PCI support and possible WPA support will have to wait for another day.
