Subject: drm/i915/guc: Move enable/disable msg functions to GuC header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: bc598425eb18d40a18f18d67f7c460189c43a3af
Patch-mainline: v4.18-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

While today we are modifying GuC enabled msg mask only in GuC
log, this code should be defined as generic GuC to allow future
code reuse.
