Add support for PS3 Linux wireless driver

This adds support for PS3 wireless to wpa_supplicant.

Although PS3 wireless driver is designed to conform the WEXT standard
as much as possible, unfortunately the wext driver wrapper of
wpa_supplicant can not support PS3 wireless fully because:

 - PS3 wireless driver uses private WEXT ioctls for accepting PSK of
   WPA-Personal from the userland.
   WEXT does not specify the way to do it.

 - The association and 4-way handshake are done by PS3 virtual
   wireless device. The guest OSes can not interfere it.

 - No EAPOL frames are allowed to go outside of the
   hypervisor/firmware nor come from. They are eaten by the firmware.

Thus I needed to make a new driver wrapper for PS3 wireless.

This patch can be applied against the latest 0.6.x tree.
