CRAS: dsp - Create dummy ini for ext_dsp_module use case
If an iodev does not use any dsp specified in dsp.ini, there will
be no dsp pipeline created.
For ext_dsp_module use case that needs a dsp pipeline to append to,
this change solves the problem by creating dummy ini to load the
simple pipeline of X ports connect from source straight to sink.
BUG=chromium:710465
TEST=Manually remove /etc/cras/dsp.ini then start playback
and recording, run 'cras_test_client --dump_dsp' then verify
in /var/log/message the pipeline dump shows N audio ports from
source to sink, for both direction.
