drm/xe: Add Xe SVM devmem_release GPU SVM vfunc
Implement with a simple BO put which releases the device memory. v2: - Use new drm_gpusvm_devmem_ops v3: - Better commit message (Thomas) v4: - Use xe_bo_put_async (Thomas) Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250306012657.3505757-27-matthew.brost@intel.com
