ath9k: implement IO serialization
All 802.11n PCI devices (Cardbus, PCI, mini-PCI) require
serialization of IO when on non-uniprocessor systems. PCI
express devices not not require this.
This should fix our only last standing open ath9k kernel.org
bugzilla bug report:
http://bugzilla.kernel.org/show_bug.cgi?id=12110
A port is probably required to older kernels and I can work on
that.
