		Enable NXP's DMA driver used by
		SOF (Sound Open Firmware) host
		component. Specifically, this driver
		is used by the SOF host component to
		perform transfers between the host
		memory and firmware (local) memory, which
		can be accessed without an actual
		DMA engine.

	help
		Use this to set the alignment (in bytes)
		which shall be used by entities employing
		this driver to adjust a memory region's size
		and base address. Since this driver doesn't
		actually have any hardware to back it up this
		configuration doesn't make much sense as there's
		no alignment restrictions imposed by memcpy.
		Nevertheless, this is needed because this driver
		needs to act as if it controls a DMA engine.
