Edayilliam Jayadev b292dd7b1a qcacmn: Use common Spectral config definition 
Today Driver and applications maintain a separate copy of
spectral config definitions, which is error prone. Solution is to
expose the definitions via a header file from driver and include
them in all applications using Spectral.
