ASoC: tas2552: Support TI TAS2552 Amplifier

Browse Source 
Support the TI TAS2552 Class D amplifier.

The TAS2552 is a high efficiency Class-D audio
power amplifier with advanced battery current
management and an integrated Class-G boost
The device constantly measures the
current and voltage across the load and provides a
digital stream of this information.

Texas Instruments - tas2552 Codec module
The tas2552 serial control bus communicates through I2C protocols
Required properties:
- compatible - One of:
"ti,tas2552" - TAS2552
- reg - I2C slave address
- supply-*: Required supply regulators are:
"vbat" battery voltage
"iovdd" I/O Voltage
"avdd" Analog DAC Voltage
Optional properties:
- enable-gpio - gpio pin to enable/disable the device
Example:
tas2552: tas2552@41 {
compatible = "ti,tas2552";
reg = <0x41>;
enable-gpio = <&gpio4 2 GPIO_ACTIVE_HIGH>;
};
