ath9k: first series for regulatory cleanup

This is the first series of general cleanup to get us into abandon our complex internal regulatory infrastructure. This is quite a lot of work as we rely on our own internal "mode" stuff and our own ath9k_channel heavily.

We start this work by ditching the mode stuff where we can and set a staging ground for us to abandon our own internal ath9k_channel. The values which we want to actually keep from ath9k_channel are the calibration data. To make use of this we will eventually map channels to our private channel structure by indexing on their position on the static array.

The next series will deal more with this and then slowly start to nuke our complex regulatory infrastructure in favor for internal generic CRDA/cfg80211 regulatory infrastructure.

This work is all being done so we won't have to malloc() all over again our new set of channels on country IE changes as doing that would be a bit messy. We will instead prefer to use static channels.

This should not have any major functional changes, its mostly cleanup stuff.

This v3 abandones the private void pointer in ieee80211_channel based on Johannes's recommendations.
