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.

* - GPIO[0] - Bluetooth interrupt of RS9113 module
|

* - GPIO[2] - HAPS interrupt (on HapsTrak 3 connector)
|
||||
* - GPIO[3] - Audio codec (MAX9880A) interrupt
|

* - GPIO[8-23] - Available on Arduino and PMOD_x headers
|
