Add missing regulator supplies for qfprom and the PCIe controllers. The qfprom node requires vcc-supply for correct eFuse reading. The PCIe controllers require vdda and vddpe-3v3 supplies for the PHY and connector power rails.
Disable the Embedded USB Debugger (EUD) as it conflicts with normal USB operation on this board.
