Subject: [PATCH v2 10/12] arm64: dts: qcom: msm8996-oneplus: Add SLPI
 VDD_PX

From: Konrad Dybcio <konrad.dybcio@....qualcomm.com>

The PX line powers some hardware related to sensors. Assume the board
doesn't reinvent what MTP has established and hook up LVS2 @ 1.8V as
such.

This fixes the 'is required' type of bindings validator errors.
