The property vddp-ref-clk-max-microamp (for VDDP ref clk supply which is l25 regulator) is not documented in MSM8996 UFS PHY bindings (qcom,msm8996-qmp-ufs-phy). It is mentioned in the other UFS PHY bindings for qcom,msm8996-ufs-phy-qmp-14nm. The MSM8996-based Xiaomi devices configure l25 regulator in a conflicting way: 1. with maximum 100 uAmp for VDDP ref clk supply of UFS PHY, 2. with maximum 450 mAmp for VCCQ supply of UFS. Since the vddp-ref-clk-max-microamp property is basically not documented for that UFS PHY and has a conflicting values, drop it entirely as it looks like not tested and not used ever.
