drm/i915: add intel_display_driver_pm_runtime*() functions
Add new functions intel_display_driver_pm_runtime_suspend(),
intel_display_driver_pm_runtime_suspend_late(),
intel_display_driver_pm_runtime_resume_early(), and
intel_display_driver_pm_runtime_resume(). The IRQ suspend/resume is
meant to happen between the corresponding calls. For now,
intel_display_driver_pm_runtime_suspend() is empty, but is included for
completeness as a placeholder.
Initially, only migrate i915, as there are some differences with xe that
will be addressed later.
There's a functional change, which should be benign:
i915_pm_runtime_resume() moves intel_opregion_notify_adapter() call
slightly later.
In the interest of not introducing more severe functional changes, the
calls become slightly asymmetric. We might want to address this later.
v2:
- Rebase, move placement of suspend calls
