drm/xe: Use usleep_range for accurate long-running workload timeslicing
commit 80f9c601d9c4d26f00356c0a9c461650e7089273 upstream.
msleep is not very accurate in terms of how long it actually sleeps,
whereas usleep_range is precise. Replace the timeslice sleep for
long-running workloads with the more accurate usleep_range to avoid
jitter if the sleep period is less than 20ms.
