libaudiohal@aidl: Work around use of unsupported mix port configurations

Sometimes the framework provides a mix port config which does not
correspond to any of profiles (likely, it's the client app config).
When it happens on stream opening, try to use the device port config.
When it happens on patch setting, try finding an existing port
config using flags and the I/O handle.
