ath9k does not provide any runtime pm callbacks, so support for
PM_RUNTIME is not needed and we could go to PM_SLEEP.
This also makes it possible to use SIMPLE_DEV_PM_OPS instead of
manually filling struct dev_pm_ops.

There are 2 different things:
- sub-menu for "Atheros Wireless cards" family
- module ath.ko with common Atheros code

Until now, they both used to depend on the same Kconfig variable ATH_COMMON.
Thus, being "Atheros card" and "depending on ath.ko" was the same.

To allow module to belong to the
"Atheros Wireless cards" family but not use ath.ko,
2 conditions above need to be separated.

So, this patch introduce new Kconfig variable ATH_CARDS for belonging
to the "Atheros Wireless Cards" family; while ATH_COMMON becomes hidden
variable to express dependency on common Atheros code in ath.ko. Modules
that depend on this common code now express it by setting ATH_COMMON.

Right now, ath6kl do not depend on common code and thus do not set ATH_COMMON.

Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Convert mac80211 (and where necessary, some drivers a
little bit) to the new channel definition struct.

This will allow extending mac80211 for VHT, which is
currently restricted to channel contexts since there
are no drivers using that which makes it easier. As
I also don't care about VHT for drivers not using the
channel context API, I won't convert the previous API
to VHT support.
Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Change nl80211 to support specifying a VHT (or HT)
using the control channel frequency (as before) and
new attributes for the channel width and first and
second center frequency. The old channel type is of
course still supported for HT.

Also change the cfg80211 channel definition struct
to support these by adding the relevant fields to
it (and removing the _type field.)

This also adds new helper functions:
 - cfg80211_chandef_create to create a channel def
   struct given the control channel and channel type,
 - cfg80211_chandef_identical to check if two channel
   definitions are identical
 - cfg80211_chandef_compatible to check if the given
   channel definitions are compatible, and return the
   wider of the two

This isn't entirely complete, but that doesn't matter
until we have a driver using it. In particular, it's
missing
 - regulatory checks on the usable bandwidth (if that
   even makes sense)
 - regulatory TX power (database can't deal with it)
 - a proper channel compatibility calculation for the
   new channel types
Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Instead of passing a channel pointer and channel type
to all functions and driver methods, pass a new channel
definition struct. Right now, this struct contains just
the control channel and channel type, but for VHT this
will change.

Also, add a small inline cfg80211_get_chandef_type() so
that drivers don't need to use the _type field of the
new structure all the time, which will change.

As mwifiex (and mac80211 in the software case) are the
only drivers actually implementing remain-on-channel
with channel type, userspace can't be relying on it.
This is the case, as it's used only for P2P operations
right now.

Rather than adding a flag to tell userspace whether or
not it can actually rely on it, simplify all the code
by removing the ability to use different channel types.
Leave only the validation of the attribute, so that if
we extend it again later (with the needed capability
flag), it can't break userspace sending invalid data.
