[PATCH v2 6/7] dt-bindings: beagle: Add BeagleConnect Freedom

[Ayush Singh]

Add devicetree bindings for the BeagleBoard.org BeagleConnect Freedom,
a wireless-enabled board based on the TI CC1352P7. The board exposes an
MCU that can be attached to a host over USB, UART, SPI or I2C, and is
described as a child node of the corresponding bus.
