As all bt packets are priority traffic during bt scan, wifi
will get disconnected when bt scan lasts for few seconds. Fix
this by allocating 10% of bt period time (4.5ms) to wifi fully.

When mac80211 was telling us to go into Powersave we listened
and immediately turned RX off. This meant hardware would not
see the ACKs from the AP we're associated with and hardware
we'd end up retransmiting the null data frame in a loop
helplessly.
Fix this by keeping track of the transmitted nullfunc frames
and only when we are sure the AP has sent back an ACK do we
go ahead and shut RX off.

The bit value of AR_GPIO_INPUT_EN_VAL_BT_PRIORITY_BB is wrong, it should
be 0x400 and the number of bits to be right shifted is 10. Having this
wrong value in 0x4054 sometimes affects bt quality on btcoex environment.

We adjust the core clock for ar9271 to 117 MHz; this also
requires us to adjust the baud divider based on the targetted
baud rate.

* Disable L1 state ONLY when device is in D3 mode.
* Clear bit 22 of register 0x4004.
* Handle power on/off properly
Not setting the workarounds properly resulted in the
disappearance of the card in certain cases.

BAR frames have to be sent to mac80211 only if the
current channel is HT. Also, move the macro to
enum ath9k_rx_filter.
