Support for NXP FMUK66 USB VID/PID

NXP Semiconductors has made the RDDRONE-FMUK66 for its HoverGames competition. The board is already supported by PX4 and hopefully will be supported in Ardupilot in the future (I believe there was some early effort some time ago).

It would be great if support for the following USB VID/PID could be added to the Mission Planner drivers.

USB_VENDOR 0x1FC9
USB_PRODUCT 0x1C
USB_STRING_MANUFACTURER "NXP"
USB_STRING_PRODUCT "RDDRONE-FMUK66"

Thanks. Please let us know if we can contribute in any way, or if more information is needed.

Start by locating the Mission Planner driver registration or configuration that maps USB vendor and product IDs, then compare it with existing board entries. Add the NXP VID 0x1FC9, product ID 0x1C, and the supplied manufacturer and product strings, and verify that the RDDRONE-FMUK66 is recognized correctly.
