drm/xe: Notify Userspace when gt reset fails
Send uevent in case of gt reset failure. This intimation can be used by
userspace monitoring tool to do the device level reset/reboot
when GT reset fails. udevadm can be used to monitor the uevents.
v2:
- Support only gt failure notification (Rodrigo)
v3
- Rectify the comments in header file.
v4
- Use pci kobj instead of drm kobj for notification.(Rodrigo)
- Cleanup (Badal)
v5
- Add tile id and gt id as additional info provided by uevent.
- Provide code documentation for the uevent. (Rodrigo)
