ACP IP have internal DMA controller, DW I2S controller and DSPs as separate power tiles. DMA and I2S devices are added to generic pm domain, so that entire IP can be powered off/on at appropriate times. Unused DSPs are made to be powered off though they are powered on during ACP pm domain power on sequence.
