boards: arm: add BeagleConnect Freedom
Add support for BeagleConnect Freedom, a TI CC1352P7 based development board with enclosure and antenna featuring BLE and SubGHz wireless, 2x mikroBUS sockets, external flash, light, temperature/humidity sensors, USB-to-UART bridge, buzzer and battery charger. See https://beagleconnect.org for details.
