The intel_display_driver_pm_suspend() calls are surrounded by near identical display calls. Move the calls inside intel_display_driver_pm_suspend().
There's a slight functional change in that intel_display_driver_pm_suspend() returns early for !HAS_DISPLAY(). Assume this is what we want, and there are no cases where display engine is present but all pipes have been fused off.
