ath9k GPIO & BT-Coex bug fixes.
Notes:
v2: fix build warning
v3: move changelog to cover letter
v4: fix [5/8] comments
Miaoqing Pan (8):
ath9k: define correct GPIO numbers and bits mask
ath9k: make GPIO API to support both of WMAC and SOC
ath9k: free GPIO resource for SOC GPIOs
ath9k: cleanup led_pin initial
ath9k: Allow platform override BTCoex pin
ath9k: add bits definition of BTCoex MODE2/3 for SOC chips
ath9k: fix BTCoex access invalid registers for SOC chips
ath9k: fix BTCoex configuration for SOC chips

1.9.1
From: Miaoqing Pan <[email protected]>
commit 61b559dea40e ("ath9k: add extra GPIO led support")
added ath9k to support access SOC's GPIOs, but implemented
in a separated API: ath9k_hw_request_gpio().
So this patch make the APIs more common, to support both
of WMAC and SOC GPIOs. The new APIs as below,
void ath9k_hw_gpio_request_in();
void ath9k_hw_gpio_request_out();
void ath9k_hw_gpio_free();
NOTE, the BSP of the SOC chips(AR9340, AR9531, AR9550, AR9561)
should set the corresponding MUX registers correctly.

From: Miaoqing Pan <[email protected]>
Define correct GPIO numbers and MASK bits to indicate the WMAC
GPIO resource.
Allow SOC chips(AR9340, AR9531, AR9550, AR9561) to access all GPIOs
which rely on gpiolib framework. But restrict SOC AR9330 only to
access WMAC GPIO which has the same design with the old chips.

From: Miaoqing Pan <[email protected]>
Make ath_init_leds() and ath_deinit_leds() pairs as the only
API to set leds, also removed direction configuration from
ath9k_start() and ath9k_stop(). So the initial is more clear
now.
