Introduce 'firmware-name' property to allow end-users and/or integrators to decide which usecase-specific firmware to run on the WCN6855. This is necessary due to resource limitations such as memory capacity and CPU capability, or performance and power optimization for different application scenarios. Two firmwares are supported: 'WCN6855/hw2.0' and 'WCN6855/hw2.0/nfa765'. The former is the default firmware, suitable for most WiFi 6 STA functions. The latter adds support for commercial-quality SAP and optimizes power consumption for IoT applications.
