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.
