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.

There is already a property "mediatek,u3p-dis-msk", prefer to use the
same format, thanks
