Mary Ruthven 910312f856 cr50: Enable RD Detection
When a debug accessory is detected by cr50, the USB controller switches
to using the CCD PHY and switches back to the AP PHY when the cable is
disconnected. This change also enables controlling the UART TX output
for the AP and EC console.

BUG=chrome-os-partner:50700
BRANCH=none
TEST=Attach suzy Q and verify the PHY is set to B. Detach Suzy Q and
check the phy has switched to A.
