Hmm, this is quite hacky, I can see why you left it all the way
to the end of the otherwise excellent series ;-)

We already have some fiq specific stuff in the
include/linux/platform_data/asoc-imx-ssi.h header file,
so I think it's best to put this declaration there, too.

If we want to eventually clean up the fiq usage in this driver,
I think we should extend the DT binding for the interrupt controller
to describe the fiq correctly so it can all be done transparently.
