arm64: dts: qcom: sc8280xp-lenovo-thinkpad-x13s: disallow regulator mode switches

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.
