habanalabs/gaudi: send device reset notification

Browse Source 
Device reset event, indicates that the device shall be reset -
after a short delay. In such case, the driver sends a notification
towards the User process. This allows the User process
to be able to take several debug actions for system
diagnostic purposes.
