dt-bindings: usb: mtu3: add optional property to disable usb2 ports 



Add support to disable specific usb2 host ports, it's useful when
a usb2 port is disabled on some platforms, but enabled on others for
the same SoC, another case is that the different package may support
different number of ports.
