ASoC: Intel: avs: Implement CLDMA transfer

Browse source

SKL and KBL rely on a dedicated HDAudio DMA stream for code loading and
authentication. The implementation of this specific mechanism for
SKL-based platforms re-uses HDAudio DMA (streaming) functions found in
HDA library to avoid duplication of functionality.
