selftests/alsa: Add a test for snd-aloop notify mode
Add a test for the hw constraints between the playback and capture
devices of an snd-aloop cable, and for the "PCM Slave" controls that
report the playback side's parameters to the capture application.
With notify disabled, a playback opened while a capture is set up must
be pinned to the capture's parameters. With notify enabled, it may pick
others. Starting it stops the running capture, and the "PCM Slave
Format", "Rate", "Channels" and "Access Mode" controls report the new
parameters, each with a value event. A capture opened second is pinned
to the playback either way.
The tests only check hw_refine results, stream states and control
values, so they don't depend on timing. They skip if snd-aloop isn't
loaded or the devices are in use.
Without "ALSA: aloop: Don't constrain playback params in notify mode",
the two notify mode tests fail.
