Subject: drm/i915/gvt: Constify intel_gvt_sched_policy_ops
Git-commit: 4642077775a65566c0d25e63bf918fb5e5235163
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
These are never modified, so make them const to allow the compiler to
put them in read-only memory.
