  links.

- Add private data. The private data is reserved for future extension.

- Add name and stream name to physical DAI links. Kernel can also use name

mixer: include library local header to find layout of structures

Inner this library, implementation of each features can find actual layout
of structures by including local header. Although, mixer feature is written
without the header and as the same way for applications. This brings some
inefficiencies such as usage of alloca() to keep memory objects for the
structures.
