Audio: Crossover: Convert to module adapter

This patch contains the changes to run crossover component as
module adapter client in IPC3 and IPC4 systems. The largest change
is to use pin indices in IPC4 instead of pipeline IDs to identify
sink streams. Pipeline IDs on firmware side are temporary in IPC4.
