drm/i915: add intel_display_driver_shutdown()

Add intel_display_driver_shutdown() to be called from the struct
pci_driver .shutdown path. Initially, only migrate i915, as there are
some subtle differences with xe that will be addressed later.

Pick up as much as we can at this point without making major functional
changes.

There's a slight functional change in that
intel_display_driver_shutdown() 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.
