CRAS: apm_list - Make echo ref tracking more reliable
Below changes are made to ensure the echo ref tracking is reliable
in apm_list regardless of how the device enable/disable events
come from cras_iodev_list.
- If APM rmod already tracking the same iodev as echo ref, don't
bother configure it again.
- If APM rmod was tracking another iodev, configure its dsp pipeline
so it no longer points back to APM rmod.
