drm/xe: Wire up device shutdown handler

Browse source

The system is turning off, and we should probably put the device
in a safe power state. We don't need to evict VRAM or suspend running
jobs to a safe state, as the device is rebooted anyway.

This does not imply the system is necessarily reset, as we can
kexec into a new kernel. Without shutting down, things like
USB Type-C may mysteriously start failing.
