Subject: [PATCH 6/6] arm64: dts: qcom: sc8180x-primus: 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.

Fixes: 2ce38cc1e8fe ("arm64: dts: qcom: sc8180x: Introduce Primus")
