ASoC: Updates for v4.14

This is quite a large release by volume of patches and diff, a lot of
that is mechanical cleanup patches but it's great to also see a range of
vendors actively working on adding new features and fixing issues in
their drivers.  Intel and Realtek have been especially active here.

 - Continued work towards moving everything to the component model from
   Morimoto-san.
 - Use of devres for jack detection GPIOs, eliminating some potential
   resource leaks.
 - Jack detection support for Qualcomm MSM8916.
 - Support for Allwinner H3, Cirrus Logic CS43130, Intel Kabylake
   systems with RT5663, Realtek RT274, TI TLV320AIC32x6 and Wolfson
   WM8523.
