intel_gt_driver_register() may be called earlier than
intel_opregion_register() and acpi_video_register(), so move it up.
intel_display_debugfs_register() may be called later, together with the
other display-related initializations. There is a slight change in
behavior that sysfs files will show up before the display-related
debugfs files, but that shouldn't be a problem - userspace shouldn't be
relying in debugfs.
This allows us to group all the display-related calls under a single
check for "HAS_DISPLAY()" that can be later moved to a better place.
