Subject: [PATCH V1 3/4] arm64: dts: qcom: sm8650: add max-microamp for UFS PHY and PLL supplies

Add `vdda-phy-max-microamp` and `vdda-pll-max-microamp` properties to
the UFS PHY node in the device tree.

These properties define the maximum current (in microamps) expected
from the PHY and PLL regulators. This allows the PHY driver to
configure regulator load accurately and ensure proper regulator mode
based on load requirements.
