This field is never set, and serves no purpose, so remove it.
I agree that we should remove it. Its been legacy support code for a
while, but the description that there is no user is not right.
The tegra20_spdif driver obviously uses it and that user is removed in
this patch. I think it makes sense to split that out into a separate
patch with a description why the driver will still work even with
slave_id removed. Maybe the best is to remove the whole tegra20_spdif
driver.

dmareq is now unused and should be removed as well.
