Module params like module_id and loadable flag can be changed
in the DSP Firmware. These are kept in the firmware manifest
and driver should read these values from this manifest.

So, add support to parse the DSP firmware manifest and
read these module params.

Some upcoming platforms like broxton etc have extended manifest
in firmware binary. This is not required to be downloaded to DSP.
So driver needs to strip this before downloading.

Add a utility function to check if a header exists, and remove it
in that case
