From 46de063efa708713349a25fb1731d2f5006fa55d Mon Sep 17 00:00:00 2001
From: Michael Strauss <michael.strauss@amd.com>
Date: Tue, 1 Oct 2019 12:04:16 -0400
Subject: [PATCH 4251/4736] drm/amd/display: Disable
force_single_disp_pipe_split on DCN2+
[WHY]
force_single_disp_pipe_split is a debug flag for use on DCN1
but isn't necessary otherwise as DCN2+ splits by default
