Gateworks 2348 and ath

[Sam Leffler]

I just posted a new ath hal for testing.  I've been using it (or similar
verisons) on my Avila boards.  The hal works fine on linux but there
appears to be a problem with interrupts on freebsd so beware.  The
symptom is that when operating in ap mode under heavy load interrupts
will stop.  I've also noticed that ath_intr is being called w/o the
pending status but set in the ath h/w so there's something not right in
the core interrupt support.  This is just fyi (and of course folks are
welcome to dig for a fix).
