Subject: drm/i915/hwconfig: Report no hwconfig support on ADL-N
Git-commit: 837c72b23a57e15dd363d5f3f3f268c49c128740
Patch-mainline: v6.0-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 jsc#PED-2849
ADL-N being a subplatform of ADL-P, it lacks support for hwconfig
table. Explicit check added to skip ADL-N.
