Currently during system s/r we enable/disable DC6, so before we do so make sure that the firmware loading is complete. Note that whether we need to enable DC6 for S3/S4 is still open. At least the firmware program is lost during S3 and we need to reprogram it after resuming. Until this is clarified we keep the current behavior and enable/disable DC6.
