For the moment this is just a placeholder, but it shows one of the main differences between the good ol' HW contexts and the shiny new Logical Ring Contexts: LR contexts allocate and free their own backing objects. Another difference is that the allocation is deferred (as the create function name suggests), but that does not happen in this patch yet, because for the moment we are only dealing with the default context. Early in the series we had our own gen8_gem_context_init/fini functions, but the truth is they now look almost the same as the legacy hw context init/fini functions. We can always split them later if this ceases to be the case. Also, we do not fall back to legacy ringbuffers when logical ring context initialization fails (not very likely to happen and, even if it does, hw contexts would probably fail as well). v2: Daniel says "explain, do not showcase".
