usb: misc: usb3503: Add to select the ports to disable
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;
