[PATCH 1/4] ASoC: SOF: Intel: hda-loader: add flag to tag ICCMAX stream

[Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>]

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.
