How much do we care about the unit tests and libraries actually test IPC? If we care a lot then we should make this at best temporary.

Unit tests and testbench bypass most of the IPC code. The SOF plugin and testbench IPC version (still a draft PR) are using the IPC library code so they would add coverage once they are ready for usage. In short term for unit tests and testbench I don't want to care much about IPC coverage but with the new frameworks I hope it gets better.
