cr50: Detect debug cable and switch the PHY
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.
