Johannes Anderwald 2d7c9100e1 [USBCCGP]
- Query bus interface and check if USBC_DEVICE_CONFIGURATION_INTERFACE_V1 is supported. This interface is implemented by attached usb filter drivers and is used to enumerate functions of the composite usb device 
- Implement enumeration of function by using usb interface association descriptors and by the USBC_DEVICE_CONFIGURATION_INTERFACE_V1
- Needs audio legacy method and union function descriptors to be fully functional
- WIP, not yet tested
- Fix build with mingw by declaring _DISK_GEOMETRY_EX outside the function
