Revert "ASoC/SoundWire: dai: expand 'stream' concept beyond SoundWire"

This reverts commit 593ca69668 which is
commit e8444560b4d9302a511f0996f4cfdf85b628f4ca upstream.

It breaks the android kernel abi and is not needed for android at this
point in time as SoundWire is not a supported configuration option.
