This lgtm, but it doesnt apply on phy/fixes Can you please rebase

According to the 'qcom,ipq5332-usb-hsphy.yaml' schema, the 5V supply regulator must be defined via the 'vdd-supply' property. The driver however requests for the 'vdda-phy' regulator which results in the following message when the driver is probed on a IPQ5018 based board with a device tree matching to the schema: qcom-m31usb-phy 5b000.phy: supply vdda-phy not found, using dummy regulator qcom-m31usb-phy 5b000.phy: Registered M31 USB phy This means that the regulator specified in the device tree never gets enabled. Change the driver to use the 'vdd' name for the regulator as per defined in the schema in order to ensure that the corresponding regulator gets enabled.
