[PATCH v2 4/5] drm/xe: Set TTM device beneficial_order to 9 (2M)

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

Set the TTM device beneficial_order to 9 (2M), which is the sweet
spot for Xe when attempting reclaim on system memory BOs, as it matches
the large GPU page size. This ensures reclaim is attempted at the most
effective order for the driver.
