Currently, sphinx emits one warning on this file:

	Documentation/driver-api/soundwire/stream.rst:522: WARNING: Block quote ends without a blank line; unexpected unindent.

That's due to some extra spaces before the title of a chapter.

Yet, the list afterwards is missing identation.

So, address both issues.

To handle streams at the dailink level, expose two helpers that will
be called from machine drivers.

The current description of stream topologies does not explicitly
mention 'mirror' topologies used for audio amplifiers, where all
amplifiers see the same data and generate a different output based on
configuration or dynamic information. Add examples and notes to
explain how channels can be transmitted and mapped.

The state machine and notes don't accurately explain or allow
transitions from STREAM_DEPREPARED and STREAM_DISABLED.

Add more explanations and allow for more transitions as a result of a
trigger_stop(), trigger_suspend() and prepare(), depending on the
ALSA/ASoC layer behavior defined by the INFO_RESUME and INFO_PAUSE
flags.

Also add basic checks to help debug inconsistent states and illegal
state machine transitions.

The way the document is written now, Sphinx renders empty code blocks
followed by the lines that should be inside them.

Unindent the code-block directives to fix this.
