drivers: bluetooth and wifi: siwx917: Introducing NWP init
WiFi and Bluetooth HCI driver was changed to use the nwp_init component. This component initializes the NWP based on the project configuration (BLE and/or WiFi). Later on the component can be modified to support common flash mode read/write/erase without BLE and WiFi. Coprocessor stack moved to a more suitable place (nwp_init). WiFi and Bluetooth advertising sample apps were tried to verify the change. Signed-off-by: Tibor Laczko <[email protected]>
