habanalabs: Timestamps buffers registration
Timestamp registration API allows the user to register
a timestamp record event which will make the driver set
timestamp when CQ counter reaches the target value
and write it to a specific location specified
by the user.
This is a non blocking API, unlike the wait_for_interrupt
which is a blocking one.
