Subject: [PATCH v9 3/3] dts: ti: k3-am625-beagleplay: Add beaglecc1352

The BeaglePlay board by BeagleBoard.org has a 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.

This mcu is used by gb-beagleplay, a Greybus driver for BeaglePlay.
