Add board/redbee-usb.cfg

The Redbee USB is a small form-factor usb stick from Redwire, LLC
(www.redwirellc.com/store), built around a Freescale MC13224V
ARM7TDMI + 802.15.4 radio (plus antenna).

It includes an FT2232H for debugging, with Channel B connected to the
mc13224v's JTAG interface (unusual) and Channel A connected to UART1.
