Unregister all in-kernel clients before unloading the i915 driver. For
other drivers, drm_dev_unregister() does this automatically. As i915 and
xe do not use this helper, they have to perform the call by themselves.
Note that there are currently no in-kernel clients in i915 or xe. The
patch prepares the drivers for a related update of their fbdev support.
v8:
- unregister clients in intel_display_driver_unregister() (Jani)
- mention xe in commit message (Rodrigo, Jani)
v7:
- update xe driver

Let's simply convert all the current callers towards direct
xe_pm_runtime access and remove this extra layer of indirection.
No functional change is expected with this patch since
xe_mem_access_get was already using the xe_pm_runtime_get_noresume
at this point.
v2: Convert all the current callers instead of a big refactor
at once.
v3: - Rebased
- Squashed the GSC/HDCP
- Added a new case: sriov_pf_policy
- Improved commit message to highlight that
there's no functional change in this patch.

At this point mem_access references should be only used as inner
points of the execution and a get with synchronous resume previously
called at an outer point.
So, before killing mem_acces in favor of direct accsess, let's
ensure that we first convert them towards the new _noresume
variant that will WARN us if no inner caller happened.

Preempt fences can sleep waiting for an exec queue suspend operation to
complete. If the system_unbound_wq is used for waiting and the number of
waiters exceeds max_active this will result in other users of the
system_unbound_wq getting starved. Use a device private work queue for
preempt fences to avoid starvation of the system_unbound_wq.
Even though suspend operations can complete out-of-order, all suspend
operations within a VM need to complete before the preempt rebind worker
can start. With that, use a device private ordered wq for preempt fence
waiting.

The GSC uC needs to communicate with the CSME to perform certain
operations. Since the GSC can't perform this communication directly on
platforms where it is integrated in GT, the graphics driver needs to
transfer the messages from GSC to CSME and back. The proxy flow must be
manually started after the GSC is loaded to signal to GSC that we're
ready to handle its messages and allow it to query its init data from
CSME.
Note that the component must be removed before the pci_remove call
completes, so we can't use a drmm helper for it and we need to instead
perform the cleanup as part of the removal flow.

XA_FLAGS_ALLOC1, adjust the xa limits at alloc_cyclic time.
v2:
- On CONFIG_DRM_XE_DEBUG, Initialize the cyclic ASID allocation in such a
way that the next allocated ASID will be the maximum one, and the one
following will cause an ASID wrap, (all to have CI test high ASIDs
and ASID wraps).
v3:
- Stricter return value checking from xa_alloc_cyclic() (Matthew Auld)

Remove unused IOCTL.
Without any userspace using it we need to remove before we
can be accepted upstream.
At this point we are breaking the compatibility for good,
so we don't need to break when we are in-tree. So, let's
also use this breakage to sort out the IOCTL entries and
fix all the small indentation and line issues.

As for display, the intent is to share the display code with the i915
driver so that there is maximum reuse there.
We do this by recompiling i915/display code twice.
Now that i915 has been adapted to support the Xe build, we can add
the xe/display support.
This initial work is a collaboration of many people and unfortunately
this squashed patch won't fully honor the proper credits.
But let's try to add a few from the squashed patches:

Driver initiated function-reset (FLR) is the highest level of reset
that we can trigger from within the driver. In contrast to PCI FLR it
doesn't require re-enumeration of PCI BAR. It can be useful in case
GT fails to reset. It is also the only way to trigger GSC reset from
the driver and can be used in future addition of GSC support.
v2:
- use regs from xe_regs.h
- move the flag to xe.mmio
- call flr only on root gt
- use BIOS protection check
- copy/paste comments from i915
v3:
- flr code moved to xe_device.c
v4:
- needs_flr_on_fini moved to xe_device

Split the PAT initialization between SW-only and HW. The _early() only
sets up the ops and data structure that are used later to program the
tables. This allows the PAT to be easily extended to other platforms.
