ASoC: Allow user-specified WM8958 multiband compressor configurations
The paramters of the WM8958 multiband compressor can be tuned by the
user for their system using a graphical configuration tool on the host.
Allow the user to specify a set of such paramters in platform data and
select between them at runtime.
