ASoC: SOF: Intel: hda-mlink: fix base_ptr computation
The base_ptr value needs to be derived from the remap_addr pointer,
not the ml_addr. This base_ptr was used only in debug logs that were
so far not contributed upstream so the issue was not detected. It
needs to be fixed for SoundWire support on LunarLake.
