Subject: [PATCH v2 2/3] phy: qcom-qusb2: Add missing vdd supply

Per downstream kernel, beside vdda-pll and vdda-phy-dpdm, vdd is also a
required supply for QUSB2 PHY digital circuit operation.  The driver
works right now likely because firmware already sets it up.  Add it for
correctness and completeness.
