Introduce a work-around for issues with the AR5416 based MAC on SMP devices.
The AR5416 MAC (which shows up in the AR5008, AR9001, AR9002 devices) has
issues with PCI transactions on SMP machines. This work-around enforces
that register access is serialised through a (global for now) spinlock.
This should stop the hangs people have seen with the AR5416 PCI devices
on SMP hosts.
