Subject: drm/i915/selftest: Extend ctx_timestamp ICL workaround to GEN11
Git-commit: 53fe9cf2dafe2b0382a4e682e4eebe0a442dcb5a
Patch-mainline: v5.15-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
EHL and JSL are also observing requirement for 80ns interval for
CTX_TIMESTAMP thus extending it to GEN11.
Changes since V1:
- IS_GEN replaced by GRAPHICS_VER - Tvrtko
