In the case of IPC4, a pipeline is only paused during STOP/PAUSE/SUSPEND triggers and the FW keeps the host DMA running when a pipeline is paused. The start/stop tests iterate through STOP/START triggers without involving a hw_free. This means that the pipeline state will only toggle between PAUSED (during the STOP trigger) and RUNNING (during the START trigger). So this test should be treated in the same way as a PAUSE_PUSH/PAUSE_RELEASE test and the DMA should be kept running when toggling the pipeline states between PAUSED and RUNNING. Since there is no way to tell if a STOP trigger will be followed by hw_free or not, this patch proposes to always skip DMA stop during the STOP trigger and handle it later during hw_free. Introduce a new flag in struct sof_ipc_pcm_ops, delayed_platform_trigger, that will be used to ensure that the host DMA will not be stopped during the STOP/PAUSE/RELEASE triggers and set it for IPC4. The platform_trigger call to stop the DMA will be invoked during PCM hw_free instead when the pipeline is reset.
