ath6kl: remove all the wext and super extended private ioctl crap

This removes all the wext and super extended ioctl crap.
The wext interfaces are already provided by cfg80211 and
the "private" ioctl stuff defined here is not even using
private wext, they are using netdev private ioctls!
This is completely unacceptable upstream. Die. Die Die.

As part of all this we end up removing the
CONFIG_HOST_GPIO_SUPPORT which ended up being heavily
abused by the internal ioctl work.
