5952880771 soundwire: stream: update state machine and add state checks
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.

9c970ab54c docs: index.rst: don't use genindex for pdf output
The genindex logic is meant to be used only for html output, as
pdf build has its own way to generate indexes.

491a3e883c Documentation: soundwire: Ensure that code is inside the code blocks
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.
