Vasanthakumar Thiagarajan 58da1318ee ath9k: Fix wifi disconnection when collocated bt scan is active
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.

Luis R. Rodriguez 8b4fc5ba89 ath9k: move ath_btcoex_config and ath_bt_mode to btcoex.c
These are only used by btcoex.c on one routine, so stuff them
into that file.

Luis R. Rodriguez 5e19729295 ath9k: now move ath9k_hw_btcoex_set_weight() to btcoex.c
After some necessary cleanups we now move ath9k_hw_btcoex_set_weight()
to where it belongs.

Luis R. Rodriguez 46289e1e5f ath9k: rename btcoex_scheme to just scheme
btcoex_scheme is already part of a btcoex struct, its implied
this is btcoex related.

Luis R. Rodriguez e08a6ace7d ath9k: move bt_stomp_type to driver core
The bt_stomp_type defines the bt coex weight, it has a one-to-one
mapping. In the future we may want to just use the weight directly.

Luis R. Rodriguez 8c1b39547e ath9k: replaces SC_OP_BTCOEX_ENABLED with a bool
Whether or not bluetooth coex has been enabled is a hardware
state and only the hardware helpers will be able to set this.

Luis R. Rodriguez 75d7839f4c ath9k: move driver core helpers to main.c
Keep on btcoex.c only hardware access helpers, move the
driver core specific code to main.c. To accomplish
this we had to split ath_init_btcoex_info() into two parts,
the driver core part -- ath_init_btcoex_timer() and the hw
specific part -- ath9k_hw_init_btcoex_hw_info(). This
highlights how ath_gen_timer is part of the driver core, not
hw related, so stuff that into ath_btcoex struct.

The ath9k_hw_btcoex_init() code is now put inline on
ath_init_softc() through a switch to it easier to follow,
since we did that we can now call ath_tx_get_qnum() from
the main.c instead of btcoex.c

Luis R. Rodriguez af03abecd8 ath9k: move hw specific btcoex info to ath_hw
Since we now access it via the ath_hw declare the ath_hw pointer
at the header of some routines and se it. ath9k.h no longer needs to
access btcoex.h and to adjust for this move ath_btcoex_set_weight()
into btcoex.h and instead give main.c a helper for setting initial
values upon drv_start()
