arm64: dts: mediatek: mt8195-cherry: Add vusb33 supplies for XHCI controllers

Like the dual-role SSUSB controller block that encompasses the XHCI
controller, the latter also takes a vusb33 supply.

Add the supply for each XHCI controller. Also fix up any property
ordering according to DT styles, i.e. move "status" property to the
end.
