Subject: [PATCH 3/3] arm64: dts: qcom: qcs615: add pcie phy max current property

Add vdda-pll-max-microamp for vdda-pll-supply. The value of this property
is from the power grid guide. It is the maximum current the regulator can
provide. The property will be parsed by PCIe PHY driver to set the current
load.
