Add support for the Broadcom based WiFi/Bluetooth module (BW3752-50B1) found in ArmSoM Sige5 boards version 1.2. This includes SDIO connected WiFi with OOB interrupt support, as well as UART connected Bluetooth with its respective interrupts. PCM support for Bluetooth SCO audio is left out for now. It is connected to SAI2 in M0 pin mode in case someone needs to enable it. Note that v1.1 boards used a Realtek based module which is incompatible with these DT nodes, so v1.1 would need a different overlay.
