Subject: drm/i915: make array states static const
Git-commit: 2a2d23b68c4e4cd71c9999ea8b8608700c3f9ead
Patch-mainline: v5.17-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
Don't populate the read-only array states on the stack but instead it
static. Also makes the object code smaller.
