pd: Set pd mux to USB 3.0 (superspeed) initially.
BRANCH=manual
BUG=chrome-os-partner:28585
TEST=manual,
Plug USB 3.0 capable device in both ports and both polarites on samus
and see device enumerate as superspeed. For example,
usb 2-3: new SuperSpeed USB device number 6 using xhci_hcd
In order you must first connected device (hoho) prior to configuring
mux via 'ectool --dev=1 --interface=lpc usbpd <port> dp'
