Trying to separate header files into net/wireless.h and
net/cfg80211.h has been a source of confusion. Remove
net/wireless.h (because there also is the linux/wireless.h)
and subsume everything into net/cfg80211.h -- except the
definitions for regulatory structures which get moved to
a new header net/regulatory.h.

The "new" net/cfg80211.h is now divided into sections.

There are no real changes in this patch but code shuffling
and some very minor documentation fixes.

I have also, to make things reflect reality, put in a
copyright line for Luis to net/regulatory.h since that
is probably exclusively written by him but was formerly
in a file that only had my copyright line.

Setup the wiphy regulatory parameters when first initializing the
Atheros regulatory module.  We can remove five exported symbols this
way and simplify the driver code for both ath5k and ath9k.

This change creates a new module, ath.ko, which includes code that can
be shared between ath5k, ath9k and ar9170. For now, extract most of the ath9k
regulatory code so it can also be used in ath5k.

All regulatory information is encapsulated by the ath9k_regulatory
struct, so we can now change all the callers to take that directly
instead of struct ath_hw.  This in turn will enable us to move the
regulatory functions to common code also used by ath5k, since both
can use this regulatory struct.

Write isWwrSKU as an inline function and nix the camel-case to make

Now that cfg80211 has its own regulatory infrastructure we can
condense ath9k's regulatory code considerably. We only keep data
we need to provide our own regulatory_hint(), reg_notifier() and
information necessary for calibration.

Atheros hardware supports 12 world regulatory domains, since these
are custom we apply them through the the new wiphy_apply_custom_regulatory().
Although we have 12 we can consolidate these into 5 structures based on
frequency and apply a different set of flags that differentiate them on
a case by case basis through the reg_notifier().

If CRDA is not found our own custom world regulatory domain is applied,
this is identical to cfg80211's except we enable passive scan on most
frequencies.
