Subject: [PATCH V1 1/4] dt-bindings: phy: Add max-microamp properties for PHY and PLL supplies

Add two new optional properties to the SC8280XP QMP UFS PHY
device tree binding:

- `vdda-phy-max-microamp`: Specifies the maximum current (in microamps)
			   that can be drawn from the PHY supply.
- `vdda-pll-max-microamp`: Specifies the maximum current (in microamps)
			   that can be drawn from the PLL supply.

These additions help define power requirements more precisely for
regulators supplying the PHY and PLL blocks and ensuring the regulators
is kept in correct mode based on the client load requirements.
