ASoC: Intel: avs: ICL-based platforms support

Define handlers specific to cAVS 2.0 platforms, that is ICL, JSL and all
other variants based on this very version of AudioDSP architecture. Most
operations are inherited from their predecessors with the major
difference being firmware-logging functionality - IPC request as well as
debug memory windows layout have changed.
