From: Yan Wang <yan.wang at linux.intel.com>

This patch set is only for initial review and trying.
It can work fine on my CNL platform.
I also tested on BYT MB, It doesn't cause regression.

  SOF: APL/CNL: Add stream_tag variable for saving parameter from kernel
    driver.
  Implement host DMA copy in existed DMA copy API.
  SOF: APL/CNL: Save stream tag and host buffer size from kernel driver.
