[PATCH v4 01/25] drm/xe: Drop struct xe_migrate_pt_update argument from populate/clear vfuns

[Matthew Brost <matthew.brost@intel.com>]

Remove the xe_migrate_pt_update argument from the populate and clear
vfuns. This structure will not be available in run_job, where CPU binds
will be implemented. The populate path no longer needs it, and the clear
path already uses the VM field instead.
