ASoC: Updates for v4.12

A quiet release for the core, but lots of new drivers this time around:

 - A new, generalized, API for hooking up jacks which makes it easier to
   write generic machine drivers for simple cases.
 - Continuing fixes for issues with the x86 CPU drivers.
 - New drivers for Cirrus CS35L35, DIO DIO2125, Everest ES7132,
   HiSilicon hi6210, Maxim MAX98927, MT2701 systems with WM8960, Nuvoton
   NAU8824, Odroid systems, ST STM32 SAI controllers and x86 systems with
   DA7213
