This adds support for RD Detection on cr50. It can be used to detect a debug device and signal the controller to switch from the AP PHY to the to CCD PHY. When RDCC1 and 2 no longer detect the debug device, then the controller switches back to using the USB to AP PHY. BUG=chrome-os-partner:50700 BRANCH=none TEST=change the value on RDCC1 and RDCC1 and check that the usb controller connects to the right PHY.
