ARM: dts: armada-38x: use usb-nop-xceiv PHY for the xhci nodes on Armada 388 GP
Using the usb-nop-xceiv PHY for the xhci nodes allows a better representation of the hardware but also a better handling of the regulator. By linking the regulator to the PHY there is no more need to use the regulator-always-on property, then it allows a better power management. The remaining usb node uses the ehci-orion driver which can't be used with the usb-nop-xceiv PHY and must keeps the direct link to the regulator with the regulator-always-on property.
