drm/xe: Move drm_dev_unplug() out of display function

This is not really display-related and needed for any sequence on driver
removal that has to interact with drm_dev_enter()/drm_dev_exit().
Just remove xe_device_remove_display() and inline it in the single
caller to make clear this is not done only for display.
