ASoC: Updates for v4.19

A fairly big update, including quite a bit of core activity this time
around (which is good to see) along with a fairly large set of new
drivers.

 - A new snd_pcm_stop_xrun() helper which is now used in several
   drivers.
 - Support for providing name prefixes to generic component nodes.
 - Quite a few fixes for DPCM as it gains a bit wider use and more
   robust testing.
 - Generalization of the DIO2125 support to a simple amplifier driver.
 - Accessory detection support for the audio graph card.
 - DT support for PXA AC'97 devices.
 - Quirks for a number of new x86 systems.
 - Support for AM Logic Meson, Everest ES7154, Intel systems with
   RT5682, Qualcomm QDSP6 and WCD9335, Realtek RT5682 and TI TAS5707.
