config cleanup

Automatic board detection

You can only build ath6kl for a static targeted chipset model. So for example you only build ath6kl to support a dual band or single band setup, plugging in a dual band chipset into an box where ath6kl was compiled into for single band support will yield with no dual band support. The same applies to Bluetooth support. The options are:

SD31: 2.4 GHz wifi
WB31: 2.4 GHz wifi + BT
SD32: 2.4 and 5 GHz wifi

We need to support all these dynamically, not statically through kconfig options. Unfortunately currently it's not know if there's any way to detect boards automatically.

AP Mode support using cfg80211
