i915_irq.c is large. It serves as the central dispatch and handler for
all of our device interrupts. Lets break it up by pulling out the GT
interrupt handlers.
Based on a patch by Chris Wilson.

i915_irq.c is large. It serves as the central dispatch and handler for
all of our device interrupts. Pull out the GT pm interrupt handling
(leaving the central dispatch) so that we can encapsulate the logic a
little better.

Avoid including the i915_drv.h mega header from other header files to
make further header cleanup easier.

No functional change, just moving the guc_to_i915 from the caller into
the irq function. This will help with the upcoming move of guc under
intel_gt.

Follow dim checkpatch recommendation so it doesn't complain on that now
and again on header file modifications.

PM interrupts belong to the GT so move the variables to be inside
struct intel_gt.

When eliminating our use of drm_irq_install() I failed to convert
all our synchronize_irq() calls to consult pdev->irq instead of
dev_priv->drm.irq. As we no longer populate dev_priv->drm.irq
we're no longer synchronizing against anything.

Move the .get_vblank_timestamp() and .get_scanout_position()
initialization to happen at compile time. No point in delaying
it since we always assign the same functions.

Switch from the driver-wide vblank vfuncs to the per-crtc ones so that
we don't have so many platform specific vfuncs in the driver struct.
We still need to do something about the rest fo the irq vfuncs...

Starting Gen11 GuC shares interrupt registers with SG unit
instead of PM. But for now we don't care about SG interrupts.

It used to be handy that we only had a couple of headers, but over time
intel_drv.h has become unwieldy. Extract declarations to a separate
header file corresponding to the implementation module, clarifying the
modularity of the driver.
Ensure the new header is self-contained, and do so with minimal further
includes, using forward declarations as needed. Include the new header
only where needed, and sort the modified include directives while at it
and as needed.
No functional changes.
