Luis R. Rodriguez 6420014ca4 ath9k: remove ath9k 25 MHz HT40 spacing stuff
This was for supporting 25 MHz spacing for HT40, this is not used
as we use 20 MHz spacing instead for HT40 as per 802.11n. The hardware
is capable of it though so we leave the phymode definition and EEPROM
parsing for it. If some experimenter wants to work on this stuff stuff
you can add an extension enabling bool on ath_common and perhaps some
debugfs knob to enable it. Keep in mind you'll also need to update the
phymode with the AR_PHY_FC_DYN2040_EXT_CH which has been left on the
driver.

Luis R. Rodriguez 9e4bffd233 atheros/ath9k: add common read/write ops and port ath9k to use it
In an effort to make hw code driver core agnostic read
and write operations are defined on the ath_common structure.
This patch adds that and makes ath9k use it. This allows
drivers like ath9k_htc to define its own read/write ops and
still rely on the same hw code. This also paves the way for
sharing code between ath9k/ath5k/ath9k_htc.

Luis R. Rodriguez 867633f026 ath9k: Define bus agnostic bluetooth coex prep helper
We disable ASPM when enabling bluetooth coexistance. Disabling
ASPM is a bus specific operation. In the future other buses may
support bluetooth coexistance, an example is USB. To this end
move the current routine which disables ASPM into pci.c, and declare
it the PCI bt_coex_prep() helper. Additionally, since ASPM is
a PCI-Express primitive ensure we don't ever try to muck with ASPM
registers on non PCI-express devices.

This also cleans up hw.c to not include bus specific headers or
utilities.

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
