Since H2G communication will be in the hot path of GuC submission, the main aim of this series is to get rid of the function pointers to speed things up and avoid retpolines (in case the compiler decides they're required). While at it, simplify the general communication enabling/disabling by removing support for multiple channels since it is extremely unlikely that we'll ever use more than one.
