soc: reduce the auto suspend timeout when swr event finished 



the APSS would suspend within ~120ms after audio off, if system suspend
swrm_suspend() is called before swrm_runtime_suspend. The clock stop
sequence require writing IPC and expect interrupt, which would stop
the APSS to be suspended. Reduce the auto suspend time specifically when
swr event is done can call the swrm_runtime_suspend
