This patchset is essentially preparation for using multiple clients for GuC submission (probably one per engine, to reduce contention). We accommodate association of each client with one or more engines, although for now we still use only one client for all engines. Switching over to one client per engine is left for a subsequent patch after the next release of GuC firmware is available.
