  Adds DT bindings for BeaglePlay CC1352 co-processor.

BeaglePlay has a CC1352 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.

It is used by gb-beagleplay greybus driver.

Zephyr bindings might be entirely different, because they are for the
case of running Zephyr OS on this processor.

I still do not fully understand whether you describe here generic MCU
used for Greybus or some specific firmware with fixed features. Looks
like the first, thus my suggestion about compatible. The location could
be arm.

By resources I mean whatever is needed to power it up and operate, e.g.
clocks, supplies, reset lines.
