drm/{i915,xe}: Unregister in-kernel clients

Unregister all in-kernel clients before unloading the i915 driver. For
other drivers, drm_dev_unregister() does this automatically. As i915 and
xe do not use this helper, they have to perform the call by themselves.

Note that there are currently no in-kernel clients in i915 or xe. The
patch prepares the drivers for a related update of their fbdev support.

v8:
- unregister clients in intel_display_driver_unregister() (Jani)
- mention xe in commit message (Rodrigo, Jani)

v7:
- update xe driver
