Subject: [PATCH 1/3] arm64: dts: qcom: sc8280xp-crd: disallow regulator mode switches

Do not allow the RPMh regulators to switch to low-power mode with an
exception for the UFS regulators (l7c and l3d) as UFS supports an idle
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.
