Currently the compressed streams in DSP firmwares are identified essentially by looking at a fixed location inside the firmware. This is fragile and also limits things to a single compressed stream. Here a new form of firmware parameter is added, the HOST_BUFFER which identifies a compressed stream from meta-data in the firmware file. This is more robust and allows for the possiblity of using multiple streams per core in the future. Currently the implementation is still limited to a single stream and will use the first HOST_BUFFER parameter encountered. If there aren't any HOST_BUFFER parameters it will fall back to the legacy way of finding the host buffer.
