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.
