wl12xx: reset link Tx queues when freeing it

Before, the link was first freed (invalidating it in the map), and later
on vif removal, all valid wlvif-related links were reset. Since these
links were already invalid, we failed to reset them.
The bug was made worse by op_stop, which set the tx_queue_count to 0
arbitrarily. This resulted in a negative tx_queue_count in some scenarios.

Fix this by resetting the Tx-queues of a link when freeing it. Add a
WARN_ON and reset all link Tx-queues in op_stop, to avoid a negative
tx_queue_count.

wl12xx: set the ELP entry delay to the FW dyn-ps timeout

With PSM handled in FW, the checks in wl1271_elp_work() are always true.
Thus during active traffic we constantly enter and exit ELP (many times
per second). As each ELP exit takes ~10ms, this can have an adverse
effect on throughput and interactivity.
Set the ELP timeout to the dyn-ps timeout. This period is longer and
avoids the above problem. It also makes sense to stay out of ELP while
we are awake on the network, to minimize delays in Tx/Rx. The same thing
was done by the mac80211 dynamic-ps mechanism before the FW DPS changes.

mac80211: fix associated vs. idle race

Eliad reports that if a scan finishes in the
middle of processing associated (however it
happens), the interface can go idle. This is
because we set assoc_data to NULL before we
set associated. Change the order so any idle
check will find either one of them.

Doing this requires duplicating the TX sync
processing, but I already have a patch to
delete that completely and will submit that
as soon as my driver changes to no longer
require it are submitted.

ath9k_hw: remove duplicate initvals

Comparing SHA1 checksums of the initval tables has shown that there are many
tables that are 100% identical.

iniBank{0,1,2,3,7} and iniBB_RfGain are shared by AR5416, AR913x, AR9160
iniBank6 is shared between AR5416 and AR9160
iniBank6TPC is shared between AR913x and AR9160

iniPcieSerdes is the same for all AR9002 based devices

The CCK FIR coefficients are shared between AR9271 and AR9287

Getting rid of those duplicates saves about 7.5k uncompressed (on MIPS).

For AR9003 and later there are some duplicates as well, but I've decided to
leave them in for now, as the initvals for those chips are still actively
maintained by QCA.

cfg80211: restructure AP/GO mode API

The AP/GO mode API isn't very clearly defined, it
has "set beacon" and "new beacon" etc.

Modify the API to the following:
 * start AP -- all settings
 * change beacon -- new beacon data
 * stop AP -- stop AP mode operation

This also reflects in the nl80211 API, rename
the commands there correspondingly (but keep
the old names for compatibility.)

Overall, this makes it much clearer what's going
on in the API.
