With the switch to an unordered workqueue dedicated to display, we've
stopped using struct drm_i915_private in a number of places, and can
drop the dependencies on i915_drv.h.

Create a new unordered workqueue to be used by the display code
instead of relying on the i915 one. Then move all the unordered works
used in the display code to use this new queue.
Since this is an unordered workqueue, by definition there can't be any
order dependency with non-display works, so no extra care is needed
in regard to that.
This is part of the effort to isolate the display code from i915.

Make i915->display pointer opaque to most of core i915 driver. Lots of
places now need explicit include of intel_display_core.h, or a more
specific header.
With this dependency broken, changes in display should cause radically
less recompilation of i915.

Pass intel_display to the encoder suspend/shutdown helpers instead of
drm_i915_private for better isolation.
v2: Pass intel_display to HAS_DISPLAY() as well, update commit log
accordingly. (Jani)

Move the encoder suspend/shutdown helpers to intel_encoder.c, this being
the logical place for encoder functions.
This also allows sharing the above helpers with the xe driver, done in a
follow-up patch.
While at it rename the functions using the usual intel_encoder prefix
and in the functions rename the dev_priv parameter to i915.
v2: Remove extra w/s in the include section. (Jani)

Recheck the link state after a passing link training, with a 2 sec delay
to account for cases where the link goes bad following the link training
and the sink doesn't report this via an HPD IRQ.
The delayed work added here will be also used by a later patch after a
failed link training to try to retrain the link with unchanged link
params before reducing the link params.
v2: Don't flush an uninitialized delayed work (on HDMI-only DDI ports).
v3:
- Move the helpers to a new intel_encoder.c file, rename them
accordingly. (Ville)
- Add the work to intel_encoder instead of intel_digital_port.
- Call the encoder specific link check function via an encoder hook.
- Flush the link check work during encoder destroy from
intel_dp_encoder_flush_work().
- Flush the link check work during encoder suspend as well.
v4: Call intel_encoder_link_check_init() with a valid encoder pointer.
