Add fields to infer UsbPortStatus and allow enabling usb while docked

Adding two fields to UsbPortStatus to infer the following:
a. usbDataStatus: To infer the current USB data status of the port.
b. powerBrickStatus: To infer whether a power brick is connected
                     to the USB port.

The change also adds a new method, enableUsbDataWhileDocked to
allow enabling Usb port while being docked.
