voicebus: Move common vpmadt032 interface into voicebus module.

The voicebus library was previously linked into both the wcte12xp and wctdm24xxp
drivers.  It is now broken out into it's own module and the common parts of the
vpmadt032 interface are now located in that module to reduce duplication between
the wcte12xp and wctdm24xxp drivers.
