Subject: drm/i915/cnp: Document WaSouthDisplayDisablePWMCGEGating
Git-commit: 470e7c6189dbce4c0d1beb8cce7e38a9bd5f5144
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

No functional change since WA is already applied.
But since it has different names on different databases,
let's document it here to avoid future confusion.
