Subject: [PATCH v4 3/3] dts: ti: k3-am625-beagleplay: Add beaglecc1352

The BeaglePlay board by BeagleBoard.org has a CC1352 co-processor. This
co-processor is connected to the main AM62 (running Linux) over UART. The
CC1352 can run Zephyr and other embedded OS. This commit adds support for
the CC1352 in the Linux kernel DTS. This allows Linux platform drivers to
identify the device and communicate with it.

This UART is used by gb-beagleplay, an upcoming Greybus driver for
BeaglePlay.
