ASoC: Updates for v3.16

Lots of cleanup work going on in the core this release but very little
visible to external users except for the new drivers that have been
added.

 - Support for specifying aux CODECs in DT.
 - Removal of the deprecated mux and enum macros.
 - More moves towards full componentisation.
 - Removal of some unused I/O code.
 - Lots of cleanups, fixes and enhancements to the davinci, Freescale,
   Haswell and Realtek drivers.
 - Several drivers exposed directly in Kconfig for use with simple-card.
 - New drivers for Cirrus CS42L56, Realtek RT5639, RT5642 and RT5651 and
   ST STA350.
