This patch is to add a property 'disabled-ports' representing the unused port
of USB3503. USB3503 can support up to 3 USB host port and each ports can be
controlled to be enabled or disabled. Do not describe this property if all
ports must be enabled.

You can represent the ports to disable in the device tree.

	usb3503@08{
		...
		disabled-ports = <2 3>;
		...
	};

This patch is to disable the USB ports unconnected to USB3503. In order to
disable the port, 'port_off_mask' must be set.

* Disable PORT1 only
	.port_off_mask = USB3503_OFF_PORT1;

* Disable PORT1 and PORT3 only
	.port_off_mask = USB3503_OFF_PORT1 | USB3503_OFF_PORT3;

* Enables all ports
	.port_off_mask = 0;
