drm-uapi: extend interface for timestamp query CPU job
Extend the UAPI to support the timestamp query user extension for the
CPU job. This user extension will allow the creation of a CPU job that
calculates the query timestamp by updating a timestamp BO with its value
and signaling the availability syncobj.
