[PATCH v4 1/3] dt-bindings: Add beaglecc1352

[Ayush Singh <ayushdevel1325@gmail.com>]

Add DT bindings for BeagleCC1352 co-processor UART.

The BeaglePlay 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 DT bindings for the BeagleCC1352
UART, which will allow Linux platform drivers to identify and access this
device.

This commit adds serial/beaglecc1352 for identifying this UART. It is
used by an upcoming gb-beagleplay greybus driver.
