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.
