However if left in IDM reset, as is the case with the Meraki and Synology NSP devices, the system will hang when probing for the PL330's AMBA peripheral ID. We therefore should be able to disable it in these cases. The PL330 is also included among of the list of peripherals put into coherent mode, so "dma-coherent" has been added here as well.
