stmhal: Fix USB CDC-only mode under Windows.
This fix adds PIDs 9801 and 9802 to the pybcdc.inf file. When in CDC only mode, it presents itself as a Communcations device rather than as a composite device. Presenting as a composite device with only the CDC interface seems to confuse windows. To test and make sure that the correct pybcdc.inf was being used, I used USBDeview from http://www.nirsoft.net/utils/usb_devices_view.html to uninstall any old pyboard drivers (Use Control-F and search for pyboard). I found running USBDeview as administrator worked best. Installing the driver in CDC+MSC mode first is recommended (since the pybcdc.inf file in on the internal flash drive). Then when you switch modes everything seems to work properly. I used https://github.com/dhylands/upy-examples/blob/master/boot_switch.py to easily switch the pyboard between the various USB modes for testing.
