60c4bf2974 ath9k_hw: remove defunct ad-hoc mode ATIM window handling code
The hardware does not have support for ATIM processing, and the driver
does not set up ah->atim_window anywhere. Additionally, the code can
clobber the timer used by P2P powersave.

0f978bfaf2 ath9k: Use a separate TX gain table for WZR-HP-G450H
The Buffalo device WZR-HP-G450H uses the index 3 for TX gain,
which is set to the high_power table currently. Later variants
of the router use the same index, but instead refer to the
low_ob_db gain table. This is not handled in the driver since
there is no way to distinguish board revisions and the high_power
table is used (incorrectly) for the newer variants.

By default, devices based on AR9300 using the TX gain index 3 have
to use the high_power table. To make sure that WZR-HP-G450H is not
broken when the high_power table is updated, use a separate array
based on information obtained from the platform data.

The current situation where only the original variant of WZR-HP-G450H
works properly stays unchanged.

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.

bf3dac5a6f ath9k: use a timer to put hardware into full sleep
When operating in client mode, the short period of time between scanning

FULL-SLEEP <-> AWAKE transitions, each wakeup requiring a reset to fully
recover the hardware.
This is completely unnecessary and can easily be avoided by deferring
the switch to full sleep.
