Subject: [PATCH v2 6/6] arm64: dts: qcom: sc8180x-lenovo-flex-5g: Allow UFS regulators load/mode setting

The UFS driver expects to be able to set load (and by extension, mode)
on the supplied regulators. Add the necessary properties to make that
possible.

Based on https://lore.kernel.org/r/20231214-topic-sc8180_fixes-v1-6-421904863006@linaro.org
