[PATCH 00/31] Reconcile i915's and xe's display power mgt sequences

[Rodrigo Vivi]

Reconcile i915's and xe's display power management sequences.

The main goal of this series is to ensure that the display
power management sequences from both drivers are fully aligned.
So, it needs to live under i915/display/ and xe_display_pm
can only be a wrapper to check for the xe's module
parameter before jumping in the i915/display functions.

During this process, it was clear that the Xe's runtime pm
sequences for integrated gfx (non d3cold capable) was totally
misaligned with i915 and prune to more bugs. So, this series ends
up fixing this and bringing a full alignment there as well.

The one new thing under i915 is the d3cold sequences. Apparently
that can be reduced, but for now this is what is validated and
stable on both DG2 and BMG. So, let's move that to the
i915/display side as well and continue on the improvements with
the code in the right place.

When I started this work I was hoping that I could run more
conversions to intel_display struct before moving things from
i915_driver.c to intel_display_driver, however that was a deeper
task and this series is already deep enough.
