Changes for VCP Driver
==============================================================================
MCUSW-326    | Clear DTR on CloseHandle().                                     



MCUSW-134    | Fixed an issue with handling of IOCTL_SERIAL_SET_WAIT_MASK,
             | IOCTL_SERIAL_WAIT_ON_MASK, with the SERIAL_EV_RXCHAR event
             | and data arriving from the device into the driver. Previously,
             | an indication of arriving data was made before making the data
             | available, causing, in some conditions, subsequent requests
             | for data after notification of data available to not deliver
             | any data. 
MCUSW-288    | Fix IOCTL_SERIAL_GET_PROPERTIES.                                
MCUSW-291    | Fix IOCTL_SERIAL_GET_PROPERTIES/SERIAL_COMMPROP for CP210x-like 
             | "Voice MB v2.0" device.
