boards: beagle: add BeaglePlay on-board CC1352P7
Add support for BeaglePlay, a TI AM6254 SoC based development board with a CC1352P7 wireless microcontroller for supporting software defined 2.4GHz and SubGHz wireless protocols. Support for running Zephyr on the quad-A53 SoC or the programmable M4 on the SoC would be provided separately. See https://beagleplay.org for details.
