Now that the PAT settings for the new special entries introduced by Xe2
are decided during early software init and left NULL on platforms they
don't apply to, there's no need to keep separate programming functions
for pre-Xe2 and post-Xe2 platforms. Consolidate down to a single pair
of programming functions (mcr and non-mcr) that can be used on any
platform.

Decide whether programming of the special ATS and PTA PAT entries is
necessary (and which entries should be programmed) during early software
initialization rather than hardcoding this into the 'program' functions.
Future platforms may want to re-use the same functions but utilize
different special entry values. Consolidating all of the decisions
into one place keeps things simple.

Introduce a new parameter to the DRM_IVPU_CMDQ_CREATE ioctl,
enabling turbo mode for jobs submitted via the command queue.
Turbo mode allows jobs to run at higher frequencies,
potentially improving performance for demanding workloads.
Also adds the IVPU_TEST_MODE_TURBO_DISABLE flag to allow test
mode to explicitly disable turbo mode requested by the application.
The IVPU_TEST_MODE_TURBO mode has been renamed to
IVPU_TEST_MODE_TURBO_ENABLE for clarity and consistency.

Add support for Wildcat Lake (WCL) CPUs.
Wildcat Lake contains NPU5 just like Panther Lake
hence the initial support is very simple and adds
only PCI IDs.

DRM drivers such as efidrm and vesadrm can export firmware EDID
data to userspace. Make the related option CONFIG_FIRMWARE_EDID
available without CONFIG_FB. Make it depend on X86, which is
currently the only architecture providing EDID information.

Currently NVMe uring_cmd completions will complete locally, if they are
polled. This is done because those completions are always invoked from
task context. And while that is true, there's no guarantee that it's
invoked under the right ring context, or even task. If someone does
NVMe passthrough via multiple threads and with a limited number of
poll queues, then ringA may find completions from ringB. For that case,
completing the request may not be sound.
Always just punt the passthrough completions via task_work, which will
redirect the completion, if needed.

Xe can free some of the data pointed to by the dma-fences it exports. Most
notably the timeline name can get freed if userspace closes the associated
submit queue. At the same time the fence could have been exported to a
third party (for example a sync_fence fd) which will then cause an use-
after-free on subsequent access.
To make this safe we need to make the driver compliant with the newly
documented dma-fence rules. Driver has to ensure a RCU grace period
between signalling a fence and freeing any data pointed to by said fence.
For the timeline name we simply make the queue be freed via kfree_rcu and
for the shared lock associated with multiple queues we add a RCU grace
period before freeing the per GT structure holding the lock.

Dma-fence objects currently suffer from a potential use after free problem
where fences exported to userspace and other drivers can outlive the
exporting driver, or the associated data structures.
The discussion on how to address this concluded that adding reference
counting to all the involved objects is not desirable, since it would need
to be very wide reaching and could cause unloadable drivers if another
entity would be holding onto a signaled fence reference potentially
indefinitely.
This patch enables the safe access by introducing and documenting a
contract between fence exporters and users. It documents a set of
contraints and adds helpers which a) drivers with potential to suffer from
the use after free must use and b) users of the dma-fence API must use as
well.
Premise of the design has multiple sides:
1. Drivers (fence exporters) MUST ensure a RCU grace period between
signalling a fence and freeing the driver private data associated with it.
The grace period does not have to follow the signalling immediately but
HAS to happen before data is freed.
2. Users of the dma-fence API marked with such requirement MUST contain
the complete access to the data within a single code block guarded by
rcu_read_lock() and rcu_read_unlock().
The combination of the two ensures that whoever sees the
DMA_FENCE_FLAG_SIGNALED_BIT not set is guaranteed to have access to a
valid fence->lock and valid data potentially accessed by the fence->ops
virtual functions, until the call to rcu_read_unlock().
3. Module unload (fence->ops) disappearing is for now explicitly not
handled. That would required a more complex protection, possibly needing
SRCU instead of RCU to handle callers such as dma_fence_release() and
dma_fence_wait_timeout(), where race between
dma_fence_enable_sw_signaling, signalling, and dereference of
fence->ops->wait() would need a sleeping SRCU context.
