ASoC: qdsp6: audioreach: add multi-port, SAL and MFC support

Merge series from Srinivas Kandagatla <srinivas.kandagatla@linaro.org>:

This patchset adds support to multi-port connections between AudioReach Modules
which is required for sophisticated graphs like ECNS or Speaker Protection.
Also as part of ECNS testing new module support for SAL and MFC are added.

Tested on SM8450 with ECNS.
