The current behavior for the runtime suspend case is that xe_display_pm_suspend_late() is only called when D3cold is allowed. Let's incorportate that behavior into a function specific to runtime PM and call it xe_display_pm_runtime_suspend_late(). With that, we keep stuff a bit more self-contained and allow having a place for adding more "late display runtime suspend"-related logic that isn't dependent on the "D3cold allowed" state.
