ASoC: SOF: ipc3-topology: Convert the topology pin index to ALH dai index
[ Upstream commit e9db1b551774037ebe39dde4a658d89ba95e260b ]
Intel SoundWire machine driver always uses Pin number 2 and above.
Currently, the pin number is used as the FW DAI index directly. As a
result, FW DAI 0 and 1 are never used. That worked fine because we use
up to 2 DAIs in a SDW link. Convert the topology pin index to ALH dai
index, the mapping is using 2-off indexing, iow, pin #2 is ALH dai #0.
The issue exists since beginning. And the Fixes tag is the first commit
that this commit can be applied.
