dt-bindings: net: Add ti,cc1352p7

Add DT bindings for Texas Instruments Simplelink CC1352P7 wireless MCU

BeaglePlay has CC1352P7 co-processor connected to the main AM62 (running
Linux) over UART. In the BeagleConnect Technology, CC1352 is responsible
for handling 6LoWPAN communication with beagleconnect freedom nodes as
well as their discovery.
