[PATCH v2] drm/xe: Modify minimum of various scheduler timeout to 0.

[Himal Prasad Ghimiray]

The sysman teams needs to disable preemption and timeslice to
test exclusivity mode and are relying on setting 'timeslice_duration_us'
and 'preempt_timeout_us' to 0 for the same. Hence set the
min configs to 0.
