drm/{i915, xe}: add intel_display_driver_pm_{suspend_late, resume_early}()

Browse source

Add new functions intel_display_driver_pm_suspend_late() and
intel_display_driver_pm_resume_early(), to be called from the
corresponding struct dev_pm_ops hooks.

There's a slight functional change for !HAS_DISPLAY() in that the new
functions return early. Assume this is what we want, and there are no
cases where display engine is present but all pipes have been fused off.
