drm/xe: Adjust long-running workload timeslices to reasonable values
A 10ms timeslice for long-running workloads is far too long and causes
significant jitter in benchmarks when the system is shared. Adjust the
value to 5ms for preempt-fencing VMs, as the resume step there is quite
costly as memory is moved around, and set it to zero for pagefault VMs,
since switching back to pagefault mode after dma-fence mode is
relatively fast.
Also change min_run_period_ms to 'unsiged int' type rather than 's64' as
only positive values make sense.
