In the future, the display code shall not have any idea about struct
xe_device or struct drm_i915_private, but will need to get at the struct
drm_device via drvdata. Store the struct drm_device pointer to drvdata
instead of the driver specific pointer.
Avoid passing NULL to container_of() via to_i915()/to_xe_device(). (It
does return NULL for NULL pointers when the offset happens to be 0, but
otherwise returns garbage pointers for NULL.)

This patch is a preparation for replacing enum i915_cache_level with PAT
index. Caching policy for buffer objects is set through the PAT index in
PTE, the old i915_cache_level is not sufficient to represent all caching
modes supported by the hardware.
Preparing the transition by adding some platform dependent data structures
and helper functions to translate the cache_level to pat_index.
cachelevel_to_pat: a platform dependent array mapping cache_level to
pat_index.
max_pat_index: the maximum PAT index recommended in hardware specification
Needed for validating the PAT index passed in from user
space.
i915_gem_get_pat_index: function to convert cache_level to PAT index.
obj_to_i915(obj): macro moved to header file for wider usage.
I915_MAX_CACHE_LEVEL: upper bound of i915_cache_level for the
convenience of coding.

We're going to introduce an additional intel_gt for MTL's media unit
soon. Let's provide a bit more multi-GT initialization framework in
preparation for that. The initialization will pull the list of GTs for
a platform from the device info structure. Although necessary for the
immediate MTL media enabling, this same framework will also be used
farther down the road when we enable remote tiles on xehpsdv and pvc.
v2:
- Re-add missing test for !HAS_EXTRA_GT_LIST in intel_gt_probe_all().
v3:
- Move intel_gt_definition struct to intel_gt_types.h. (Jani)
- Drop gtdef->setup(). For now we'll just use a switch() based on GT
type since we don't have too many different handlers for the
foreseeable future. (Jani)

rerere cache update")]
We now support a per-gt uncore, yet we're not able to infer which GT
we're operating upon. Let's store a backpointer for now.
At this point the early initialization of the gt needs to be
broken in two parts where the first is needed to assign to the gt
the i915 private data pointer and the uncore. A temporary
function has been made and the two parts are
__intel_gt_init_early() and intel_gt_init_early(). This split
will be fixed in the future with the multitile patch.

When running the GuC the GPU can't be considered idle if the GuC still
has contexts pinned. As such, a call has been added in
intel_gt_wait_for_idle to idle the UC and in turn the GuC by waiting for
the number of unpinned contexts to go to zero.

To avoid having to create all the device and driver scaffolding we
just manually create and destroy a devres_group.
v2: Rebased
v3: use devres_open/release_group so we can use devm without real
hacks in the driver core or having to create an entire fake bus for
testing drivers. Might want to extract this into helpers eventually,
maybe as a mock_drm_dev_alloc or test_drm_dev_alloc.
v4:
- Fix IS_ERR handling (Matt)
- Delete surplus put_device() in mock_device_release (intel-gfx-ci)
v5:
- do not switch to device_add - it breaks runtime pm in the tests and
with the devres_group_add/release no longer needed for automatic
cleanup (CI). Update commit message to match.
- print correct error in pr_err (Matt)
v6: Remove now unused err variable (CI).
v7: More warning fixes ...
