ath9k: Fix crash in MCC mode
When a channel context is removed, the hw_queue_base
is set to -1, this will result in a panic because
ath9k_chanctx_stop_queues() can be called on an interface
that is not assigned to any context yet - for example,
when trying to scan.
Fix this issue by setting the hw_queue_base to zero
when a channel context is removed.

ath9k: Fix flushing in MCC mode
When we are attempting to switch to a new
channel context, the TX queues are flushed, but
the mac80211 queues are not stopped and traffic
can still come down to the driver.
This patch fixes it by stopping the queues
assigned to the current context/vif before
trying to flush.

ath9k: Fix queue handling for channel contexts
When a full chip reset is done, all the queues
across all VIFs are stopped, but if MCC is enabled,
only the queues of the current context is awakened,
when we complete the reset.
This results in unfairness for the inactive context.
Since frames are queued internally in the driver if
there is a context mismatch, we can awaken all the
queues when coming out of a reset.
The VIF-specific queues are still used in flow control,
to ensure fairness when traffic is high.

ath9k: Fix queue handling in flush()
When draining of the TX queues fails, a
full HW reset is done. ath_reset() makes sure
that the queues in mac80211 are restarted,

ath9k: fix getting tx duration for dynack
On AR9003, tx control and tx status are in separate descriptor rings.
Tx duration is extracted from the tx control descriptor data, which
ar9003_hw_proc_txdesc cannot access.
Fix getting the duration by adding a separate callback for it.

ath9k_hw: fix PLL clock initialization for newer SoC
On AR934x and newer SoC devices, the layout of the AR_RTC_PLL_CONTROL
register changed. This currently breaks at least 5/10 MHz operation.
AR933x uses the old layout.
It might also have been causing other stability issues because of the
different location of the PLL_BYPASS bit which needs to be set during
PLL clock initialization.
This patch also removes more instances of hardcoded register values in
favor of properly computed ones with the PLL_BYPASS bit added.

ath9k_hw: reduce ANI spur immunity setting on HT40 extension channel
The cycpwr_thr1 value needs to be lower on the extension channel than on
the control channel, similar to how the register settings are programmed
in the initvals.
Also drop the unnecessary check for HT40 - this register can always be
written. This patch has been reported to improve HT40 stability and
throughput in some environments.

ath9k_hw: disable hardware ad-hoc flag on ar934x rev 3
On AR934x rev 3, settin the ad-hoc flag completely messes up hardware
state - beacons get stuck, almost no packets make it out, hardware is
constantly reset.
When leaving out that flag and setting up the hw like in AP mode, TSF
timers won't be automatically synced, but at least the rest works.
