Bandan Das - Sept. 5, 2013, 10:24 p.m.
Define PARAM so that we have two versions of the "desc_codec 
and family" structs. Add a property called "mixer" whose default
value depends on whether CONFIG_MIXEMU is defined or not which
will help us call the appropriate instance init functions.

Indeed, they are not needed anymore. Thanks for the catch. I will fix this in a follow-up
post.

This is not needed as I already undef this in the header file.
