AMD SoundWire manager supports different power modes. acp_reset flag will be set to false only when SoundWire manager power mode is selected as ClockStop Mode. For rest of the combinations (ACP PDM + SDW), acp_reset flag will be set to true. When acp_reset flag is set, acp de-init and acp init sequence should be invoked during suspend/resume callbacks.
