Subject: [PATCH 6.0 430/862] arm64: dts: qcom: sc8280xp-lenovo-thinkpad-x13s: disallow regulator mode switches

From: Johan Hovold <johan+linaro@...nel.org>

[ Upstream commit 648ec2f2ddc05346287e308fbc31a6b8117a1edd ]

Do not allow the RPMh regulators to switch to low-power mode.

This specifically avoids having regulators be but in low-power mode when
only some consumers specify loads while the actual total load really
warrants high-power mode.
