Subject: [PATCH v6 1/3] dt-bindings: Add beaglecc1352

Add DT bindings for BeaglePlay CC1352 co-processor.

The BeaglePlay has a CC1352 co-processor. This co-processor is 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

This commit adds net/ti,cc1352p7. It is used by gb-beagleplay greybus
driver.
