freebsd-dev/sys/contrib/dev/ath/ath_hal/ar9300/ar9300_mci.c
Adrian Chadd e113789bdc Bring over my FreeBSD modifications for the AR9300 HAL to make it 
work in FreeBSD.

This is still heavily a work in progress but I'd rather it start
shipping in -HEAD sooner rather than later.

This doesn't (yet) link it into the build system either for a static
kernel or as a module; that will come later (after many, many make universe
tests.)
