The previous patch has split up the initialization of some of the GuC
objects in 2 different functions, let's pull them back together.
v3: Group initialization of GuC objects
v2: Decoupling ADS together with logs (Daniele)
v3: Rebase
v4: Rebase
v5: Separated from previous patch

Hmm, is "stage_ids" also considered as "shared object" ?
See ida_init(&guc->stage_ids); later in this function.
also, since function starts with "i915" there is no reason to change
parameter from dev_priv to guc
I was actually undecided if this change was worth doing. It seems to be
a better
idea to keep the guc_submission stuff separate at an higher level.
