staging: bcm2835-audio: Remove redundant spdif stream ctls
commit
ab91e26229eaca2832df51e13c1285aea3be33ab upstream.
The "IEC958 Playback Stream" control does basically the very same
thing as "IEC958 Playback Default" redundantly. The former should
have been stream-specific and restored after closing the stream, but
we don't do in that way.
Since it's nothing but confusion, remove this fake.
