Subject: [PATCH] drm/i915/guc: Use GUC prefix for CORE_FAMILY definitions
Git-commit: b53af8bb18b85188b5c8cacaa6a966774b548f17
Patch-mainline: v4.13-rc1
References: FATE#322643 bsc#1055900

Almost all other GuC fw definitions are using GUC|guc prefix.
While around, in get_core_family() change explicit WARN into MISSING_CASE
as it looks more appropriate, since GuC support capability we are controlling
by intel_device_info.has_guc flag.
