We can propagate better errors upon failed hw initialization,
and set up the ath_common structure for attach purposes. This
will become important once we start using the ath_common
for read/write ops.

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.

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.

The ah_sta_id was really being used as the macaddr.
ath5k still does not use the association ID now passed
up by mac80211, that can be fixed later.

These are common amongst ath9k and ath5k, so put them into the
common structure and make ath9k to use it. ar9170 can use macaddr,
and curbssid. We'll change ath5k and ar9170 separately.

Historically some macro helpers have been users for this,
AR5K_LOW_ID() and AR5K_HIGH_ID(), use upstream unaligned
helpers instead. This applid to ath5k and ar9170. ath9k
already uses this.
Worth noting is ath5k uses an ah_sta_id but that is already
the MAC address combined with the associaiton ID, ah_sta_id
is really ETH_ALEN in size.

ath9k_hw_setpower() is a core driver helper with locking
protection. Locking protection should be left to the driver
core, not the hw code. Hardware code no longer contends for
locking when it needs to wake up the chip or put it to sleep.

When the TSF is reset power save state is disabled and
then restored. The helpers to disable power save and restore
it use a lock provided by the driver core. Move the callers
of the helpers outside of the hw code.
We reset the TSF when mac80211 tells us and on the beacon.c
helper ath9k_hw_beaconinit() when it is made explicitly required.
Add a helper on beacon.c which will deal with ps awake/restore
if we need to reset the TSF upon ath9k_hw_beaconinit().
