drm/sched: Rename priority MIN to LOW

Rename DRM_SCHED_PRIORITY_MIN to DRM_SCHED_PRIORITY_LOW.

This mirrors DRM_SCHED_PRIORITY_HIGH, for a list of DRM scheduler priorities
in ascending order,
  DRM_SCHED_PRIORITY_LOW,
  DRM_SCHED_PRIORITY_NORMAL,
  DRM_SCHED_PRIORITY_HIGH,
  DRM_SCHED_PRIORITY_KERNEL.
