Program FIFO trigger level properly to fix x4 accelerated playback.

Fixes like this should really go before any new stuff so they can be
sent as fixes and backported.

This driver never worked before this patchset, hence there is nothing to
backport, this is explained in the cover letter. But in general you're
correct.

That's not going to stop the stable people backporting things, and I'd
guess it might've worked at some point on some systems - I'm not seeing
anything that jumps out as making the driver completely unworkable in
your patches.

I can change commit message with the "fix" word removed, this should
prevent patch from backporting.

This driver never worked in mainline because S/PDIF device was never
created, thus driver was never bound. Driver doesn't work properly
without this patch. Nobody used this driver as-is before this patchset.
