ASoC: SOF: Intel: hda-loader: add flag to tag ICCMAX stream

The existing code conflates capture stream and ICCMAX stream. This
isn't going to be true any longer when we add support for SDW BPT RX
streams. Add a boolean tag to flag ICCMAX streams.

No functionality change, only future-proofing change.
