1aff1903d0 drm/i915: Hide unshrinkable context objects from the shrinker 
The shrinker cannot touch objects used by the contexts (logical state
and ring). Currently we mark those as "pin_global" to let the shrinker
skip over them, however, if we remove them from the shrinker lists
entirely, we don't event have to include them in our shrink accounting.

By keeping the unshrinkable objects in our shrinker tracking, we report
a large number of objects available to be shrunk, and leave the shrinker
deeply unsatisfied when we fail to reclaim those. The shrinker will
persist in trying to reclaim the unavailable objects, forcing the system
into a livelock (not even hitting the dread oomkiller).

v2: Extend unshrinkable protection for perma-pinned scratch and guc
allocations (Tvrtko)
v3: Notice that we should be pinned when marking unshrinkable and so the
link cannot be empty; merge duplicate paths.

6f76098fe0 drm/i915/uc: Move uC early functions inside the GT ones 
uC is a subcomponent of GT, so initialize/clean it as part of it. The
wopcm_init_early doesn't have to be happen before the uC one, but since
in other parts of the code we consider WOPCM first do the same for
consistency.

v2: s/cleanup_early/late_release to match the caller
v3: s/late_release/driver_late_release/ (Chris)

6cf72db68d drm/i915/gt: Move gt_cleanup_early out of gem_cleanup_early 
We don't call the init_early function from within the gem code, so we
shouldn't do it for the cleanup either.

cb823ed991 drm/i915/gt: Use intel_gt as the primary object for handling resets 
Having taken the first step in encapsulating the functionality by moving
the related files under gt/, the next step is to start encapsulating by
passing around the relevant structs rather than the global
drm_i915_private. In this step, we pass intel_gt to intel_reset.c

db56f97494 drm/i915: Eliminate dual personality of i915_scratch_offset 
Scratch vma lives under gt but the API used to work on i915. Make this
consistent by renaming the function to intel_gt_scratch_offset and make
it take struct intel_gt.

a1c8a09e0c drm/i915: Convert i915_gem_flush_ggtt_writes to intel_gt 
Having introduced struct intel_gt (named the anonymous structure in i915)
we can start using it to compartmentalize our code better. It makes more
sense logically to have the code internally like this and it will also
help with future split between gt and display in i915.

v2:
 * Keep ggtt flush before fb obj flush. (Chris)

v3:
 * Fix refactoring fail.
 * Always flush ggtt writes. (Chris)
