Enable the ALWAYS_KEYSEARCH bit in the initvals. Currently
this is done in the driver, but adding this to the initvals

bbf807bc06 ath9k: fix duration calculation for non-aggregated packets
When not aggregating packets, fi->framelen should be passed in as length
to calculate the duration. Before the tx path rework, ath_tx_fill_desc
was called for either one aggregate, or one single frame, with the
length of the packet or the aggregate as a parameter.
After the rework, ath_tx_sched_aggr can pass a burst of single frames to
ath_tx_fill_desc and sets len=0.
Fix broken duration calculation by overriding the length in ath_tx_fill_desc
before passing it to ath_buf_set_rate.

251c9ba191 ath: fix dynamic user regulatory domain support
As it stands dynamic user regulatory domain support is
only possible for a few programmed regulatory domains as
a few countries do not allow for this.

The existing code however only would take advantage of
the feature if a custom world regulatory domain is used
though as that's when we clear beconing flags. We need
to lift this restriction as otherwise this feature is
pointless.

bc0aa06918 ath: clean up ath_reg_apply_active_scan_flags()
The routine ath_reg_apply_active_scan_flags() can be a bit
hard to read, this cleans it up by adding helpers for the
two cases of clearing IR flags or adding them. This approach
also makes no assumptions on the index of channels 12 and 13
so it should be portable accross different drivers.

09d8e315d9 ath9k_hw: fix TSF save/restore around chip reset
A cold reset can be triggered because of DMA stop issues, and this leads
to TSF being cleared on all chipsets. To properly deal with this, always
save the TSF.
Additionally, account for the time it takes to do the actual chip reset,
which can be quite significant. On AR9344 it takes around 4.5 ms.
