Assume that intel_wakereg_get() may take the mutex, and perform other
sleeping actions in the course of its callbacks and so use might_sleep()
to ensure that all callers abide. Anything that cannot sleep has to use
e.g. intel_wakeref_get_if_active() to avoid hitting the non-atomic
paths.

In the event a platform does not properly implement reset,
do not go through reset flows for engine domains to avoid
an unlikely situation where writes are accepted but register
values are never cleared, as this can result in GPU wedges
in these cases.

Implement Wa_1604555607 (set the DS pairing timer to 128 cycles).
FF_MODE2 is part of the register state context, that's why it is
implemented here.
v2: Rebased on top of the WA refactoring (Oscar)
v3: Correctly add to ctx_workarounds_init (Michel)
v4:
uncore read is used
At TGL A0 stepping, FF_MODE2 register read back is broken, hence
disabling the WA verification.
Helper function called wa_write_masked_or_no_verify is defined for the
same purpose.

Implements the Wa_1604555607 and skips its verification as the FF_MODES2
register is writeonly till TGL B0.

Now that we never allow the intel_wakeref callbacks to be invoked from
interrupt context, we do not need the irqsafe spinlock for the timeline.

The general concept was that intel_timeline.active_count was locked by
the intel_timeline.mutex. The exception was for power management, where
the engine->kernel_context->timeline could be manipulated under the
global wakeref.mutex.
This was quite solid, as we always manipulated the timeline only

In commit a79ca656b648 ("drm/i915: Push the wakeref->count deferral to
the backend"), I erroneously concluded that we last modify the engine
inside __i915_request_commit() meaning that we could enable concurrent
submission for userspace as we enqueued this request. However, this
falls into a trap w
