Subject: drm/i915/icl: Fix DC9 Suspend for ICL.
Git-commit: 3b6ac43b48576d7b38539c31b4e370b2e942c3aa
Patch-mainline: v5.0-rc1
References: fate#326289

Add missing block that takes care of inline intel_suspend_complete
for DC9 on ICL.

Daniele noticed this was part of original patch but missed on
on merged commit ("drm/i915/icl: Enable DC9 as lowest possible
 state during screen-off").
