This patch fixes a bug in ath9k_stop() where the HW
was not put into FULL_SLEEP state. Not doing so will
cause issues in suspend-resume and the HW will not respond
to chip resets.

ath9k supports the AR9002 family of chipsets. This includes
the AR9285 and the miniPCI AR9223 and AR9220 (which themselves
have AR9280+AR5133).
We now refer people to the wiki page as it seems this is not
as popular as we would have hoped.

Turns out ath5k and ath9k can share the same helper to
allocates RX skbs. We allocate skbs aligned to the cache line
size. This requirement seems to have come from AR5210; when
this was not done it seems sometimes we'd get bogus data. I'm
also told it may have been a performance enhancement
consideration. In the end I can't be sure we can remove this
on new hardware so just keep this and start sharing it through
ath.ko.
Make ath9k start using this, ath5k is next.

In the the patch:
ath9k: use new FIF_PSPOLL configure filter
I forgot to add the new FIF_PSPOLL to the supported mask.
Without this we mask out the FIF_PSPOLL flag therefore
we'd ignore it from mac80211.

If hw initialization fails (ath9k_hw_init()) on ath_init_softc()
we bail out and call ath9k_hw_detach(). The call ath9k_hw_detach()
is conditional though as ath9k_hw_init() could itself have called
ath9k_hw_detach(). Just describing this is itself a brain twister.
Avoid this nonsense by removing ath9k_hw_detach() from ath9k_hw_init().
Upon hw initialization failure we expect the callers to take care of
the cleanup.
