The worker is canceled in gt_park path, but earlier it was assumed that
gt_park path cannot sleep and the cancel is asynchronous. This caused a
race with suspend flow where the worker runs after suspend and causes an
unclaimed register access warning. Cancel the worker synchronously since

DRM_DEBUG is not the right debug call to use in i915 OA, replace it with
driver specific drm_dbg() call (Matt).

The global sseu config is applicable only to gen11 platforms where
concurrent media, render and OA use cases may cause some subslices to be
turned off and hence lose NOA configuration. Ideally we want to return
ENODEV for non-gen11 platforms, however, this has shipped with gfx12, so
disable only

For execlists backend, current implementation of Wa_22011802037 is to
stop the CS before doing a reset of the engine. This WA was further
extended to wait for any pending MI FORCE WAKEUPs before issuing a
reset. Add the extended steps in the execlist path of reset.

GuC provides engine_id and last_switch_in ticks for an active context in
the pphwsp. The context image provides a 32 bit total ticks which is the
accumulated by the context (a.k.a. context[CTX_TIMESTAMP]). This
information is used to calculate the context busyness as follows:

In addition, extend the WA to gen11.
v2: (Tvrtko)
- Clarify comments, commit message, fix typos
- Use IS_GRAPHICS_VER for gen 11/12 checks
v3: (Daneile)
- Drop changes to intel_ring_submission since WA does not apply to it
- Log an error if MSG IDLE is not defined
