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.

Until ath5k and ath9k share common channel structures, they will have
to implement their own get_ctl() function. Split out the portion that
only relies on the current band and reg domain so that it can be common
code.

regulatory domain and provide details of the request.

This is not used as we can always just assume the first
regulatory domain set will _always_ be a static regulatory
domain. REGDOM_SET_BY_CORE will be the first request from
cfg80211 for a regdomain and that then populates the first
regulatory request.

This is the initial step in allowing ath9k to register multiple
virtual radios (wiphys). The goal of virtual radios is to allow the
same radio to be shared for multiple virtual interfaces that may
operate on different channels. The mac80211 virtual interface support
is designed only for single channel operation and as such, it is not
suitable for this type of use. Anyway, it can be used on top of the
virtual radio concept, if desired (e.g., use two virtual radios to
handle two channels and then add multiple mac80211 virtual interfaces
on top of each virtual radio).
The new struct ath_wiphy is now registered as the driver data
structure for wiphy. This structure has a pointer to the shared (among
virtual wiphys of the same physical radio) struct ath_softc data. The
primary wiphy maintains the allocated memory for ath_softc. Secondary
(virtual) wiphys will only allocate the new ath_wiphy structure.
Registration of secondary wiphys is added in a separate patch.

Write isWwrSKU as an inline function and nix the camel-case to make
the routine slightly clearer. Change its argument to take the regd
value directly so it can eventually be used by ath5k as well.

If we have new found information about our location and the
current country regulatory domain does not have passive scan
flag requirements we should be able to actively scan now on those
channels.
Since AP functionality is not allowed where passive scan flags are
set this means if you have a world regulatory domain and you get a
country IE that allows that channel (with active scan) then we lift
the passive-scan requirement so you can then use AP mode.

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.
