[PATCH v6 4/5] drm/xe/drm_ras: Wire up error threshold callbacks

Now that we have get/set error threshold support in xe driver, wire them
up to drm_ras so that userspace can make use of the functionality.

$ sudo ynl --family drm_ras --do get-error-threshold \
--json '{"node-id":0, "error-id":2}'
{'error-id': 2, 'error-name': 'soc-internal', 'error-threshold': 16}

$ sudo ynl --family drm_ras --do set-error-threshold \
--json '{"node-id":0, "error-id":2, "error-threshold":8}'
None
