Subject: [PATCH 6.7 148/713] arm64: dts: qcom: sc8180x: Require LOW_SVS vote for MMCX if DISPCC is on

From: Konrad Dybcio <konrad.dybcio@...aro.org>

[ Upstream commit 6d9fb9e4c473cdfd2adca019b46d8e482105cae7 ]

To ensure the PLLs are getting enough power, cast a vote with DISPCC so
that MMCX is at least at LOW_SVS.
