CRAS: New --dsp_config CLI option

Add a command line option to specify the location of the DSP config
file.

This can be used if there are more than one dsp.ini files for a given
system.  This happens when systems are build with different speakers or
mechanicals.

TEST=pass command --dsp_config and see what it loads
