Add a policy to handle the case where the device can source the `CONFIG_USB_PD_MAX_SINGLE_SOURCE_CURRENT` over one of its type-C port if there is no sink connected on the other ones. Signed-off-by: Vincent Palatin <vpalatin@chromium.org> BRANCH=none BUG=chrome-os-partner:56110 TEST=manual: on Kevin, plug and unplug various devices on the 2 ports, while measuring the type-C pull-up with Twinkie.
