pi3usb9201: Add EC console log for host CDP mode setting
For the pi3usb9201 the usb D+/D- switches are closed automatically
based on either the result of bc1.2 client detection completion or
setting CDP_HOST mode. There is a console log already that shows the
bc1.2 client mode detection result. However, for host mode there was
no console log. This CL adds a message when this setting is used which
is useful for knowing for certain that the D+/D- switches have been
closed.
