ASoC: tlv320aic31xx: Add basic codec driver implementation 

This commit adds a bare bones driver support for TLV320AIC31XX family
audio codecs. The driver adds basic stereo playback trough headphone
and speaker outputs and mono capture trough microphone inputs.

The driver is currently missing support at least for mini DSP features
and jack detection. I have tested the driver only on TLV320AIC3111,
but based on the data sheets TLV320AIC3100, TLV320AIC3110, and
TLV320AIC3120 should work Ok too.

The base for the implementation was taken from:
git@gitorious.org:ti-codecs/ti-codecs.git ajitk/topics/k3.10.1-aic31xx
-branch at commit 77504eba0294764e9e63b4a0c696b44db187cd13.

Texas Instruments - tlv320aic31xx Codec module
The tlv320aic31xx serial control bus communicates through I2C protocols
Required properties:
- compatible - "string" - One of:
"ti,tlv320aic310x" - Generic TLV320AIC31xx with mono speaker amp
"ti,tlv320aic311x" - Generic TLV320AIC31xx with stereo speaker amp
"ti,tlv320aic3100" - TLV320AIC3100 (mono speaker amp, no MiniDSP)
"ti,tlv320aic3110" - TLV320AIC3110 (stereo speaker amp, no MiniDSP)
"ti,tlv320aic3120" - TLV320AIC3120 (mono speaker amp, MiniDSP)
"ti,tlv320aic3111" - TLV320AIC3111 (stereo speaker amp, MiniDSP)
- reg - <int> - I2C slave address
Optional properties:
- gpio-reset - gpio pin number used for codec reset
- ai31xx-micbias-vg - MicBias Voltage setting
1 or MICBIAS_2_0V - MICBIAS output is powered to 2.0V
2 or MICBIAS_2_5V - MICBIAS output is powered to 2.5V
3 or MICBIAS_AVDD - MICBIAS output is connected to AVDD
If this node is not mentioned or if the value is unknown, then
micbias is set to 2.0V.
- HPVDD-supply, SPRVDD-supply, SPLVDD-supply, AVDD-supply, IOVDD-supply,
DVDD-supply : power supplies for the device as covered in
Documentation/devicetree/bindings/regulator/regulator.txt
CODEC output pins:
* HPL
* HPR
* SPL, devices with stereo speaker amp
* SPR, devices with stereo speaker amp
* SPK, devices with mono speaker amp
* MICBIAS
CODEC input pins:
* MIC1LP
* MIC1RP
* MIC1LM
The pins can be used in referring sound node's audio-routing property.
Example:
#include <dt-bindings/sound/tlv320aic31xx-micbias.h>
tlv320aic31xx: tlv320aic31xx@18 {
compatible = "ti,tlv320aic311x";
reg = <0x18>;
ai31xx-micbias-vg = <MICBIAS_OFF>;
HPVDD-supply = <&regulator>;
SPRVDD-supply = <&regulator>;
SPLVDD-supply = <&regulator>;
AVDD-supply = <&regulator>;
IOVDD-supply = <&regulator>;
DVDD-supply = <&regulator>;
};
