This enables forwarding of the local PD/EC console
over debug USB. It gates the console functionality
based on the CCD mode that is set.

Enable partial CCD mode on ryu and verify that it is
enumerated by the host correctly, but doesn't respond
to console input, and doesn't generate output.
Enable full CCD mode on ryu and verify that it is
enumerated and that the console works as expected.
Verify that the console still works by default on the
discovery-stm32f072 board.

This provides a framework for additional work. It
exposes an API (ccd_set_mode) that can be used by the
PD code to enable Case Closed Debug. Enabling CCD will
result in the USB 2.0 lines on Ryu (proto 2) to be
disconnected from the AP and for the USB peripheral to
be enabled and connected to the host. The result is
an enumerated device with no interfaces.

Enable CCD ryu_p2 and verify that it is enumerated
by the host correctly. This requires a reworked
Ryu (proto 2 with pullup).
