sound updates for 4.14-rc1 

We have touched quite a lot of files but with fewer changes at this
 cycle; as you can see, most of changes are trivial fixes, especially
 constification patches.  Among the massive attacks by constification
 gangs, we had a few core changes (mostly for ASoC core), as well the
 fixes and the updates by major vendors.  Some highlights are below:
 
 ALSA core:
 - Fix possible races in control API user-TLV codes
 - Small cleanup of PCM core
 
 ASoC:
 - Continued work for componentization; still half-baked, but we're
   certainly progressing
 - Use of devres for jack detection GPIOs, rather as a cleanup
 - Jack detection support for Qualcomm MSM8916
 - Support for Allwinner H3, Cirrus Logic CS43130, Intel Kabylake
   systems with RT5663, Realtek RT274, TI TLV320AIC32x6 and Wolfson

Documentation/devicetree/bindings/regulator/regulator.txt.
Optional properties:
- reset-gpios : Active low GPIO used to reset the device
- cirrus,xtal-ibias:
When external MCLK is generated by external crystal
oscillator, CS43130 can be used to provide bias current
for external crystal. Amount of bias current sent is
set as:
1 = 7.5uA
2 = 12.5uA
3 = 15uA
- cirrus,dc-measure:
Boolean, define to enable headphone DC impedance measurement.
- cirrus,ac-measure:
Boolean, define to enable headphone AC impedance measurement.
DC impedance must also be enabled for AC impedance measurement.
- cirrus,dc-threshold:
Define 2 DC impedance thresholds in ohms for HP output control.
Default values are 50 and 120 Ohms.
- cirrus,ac-freq:
Define the frequencies at which to measure HP AC impedance.
Only used if "cirrus,dc-measure" is defined.
Exactly 10 frequencies must be defined.
If this properties is undefined, by default,
following frequencies are used:
<24 43 93 200 431 928 2000 4309 9283 20000>
