ASoC: Updates for v4.17

This is a *very* big release for ASoC.  Not much change in the core but
there s the transition of all the individual drivers over to components
which is intended to support further core work.  The goal is to make it
easier to do further core work by removing the need to special case all
the different driver classes in the core, many of the devices end up
being used in multiple roles in modern systems.

We also have quite a lot of new drivers added this month of all kinds,
quite a few for simple devices but also some more advanced ones with
more substantial code.

 - The biggest thing is the huge series from Morimoto-san which
   converted everything over to components.  This is a huge change by
   code volume but was fairly mechanical
 - Many fixes for some of the Realtek based Baytrail systems covering
   both the CODECs and the CPUs, contributed by Hans de Goode.
 - Lots of cleanups for Samsung based Odroid systems from Sylwester
   Nawrocki.
 - The Freescale SSI driver also got a lot of cleanups from Nicolin
   Chen.
 - The Blackfin drivers have been removed as part of the removal of the
   architecture.
 - New drivers for AKM AK4458 and AK5558, several AMD based machines,
   several Intel based machines, Maxim MAX9759, Motorola CPCAP,
   Socionext Uniphier SoCs, and TI PCM1789 and TDA7419
