From: Konrad Dybcio <konrad.dybcio@linaro.org>
Subject: arm64: dts: qcom: sc7280: Add the missing MDSS icc path
Date: Wed, 29 Nov 2023 15:44:04 +0100
MDSS, aside from the MDP-MEM path, also requires the CPU-DISP_CFG one.
Failing to provide it may result in register accesses failing and that's
never good.
Add the missing path.
