ASoC: Final updates for v3.20 

A few more updates for v3.20 that have accumilated over the second half
 of last week.  One new (relatively simple) driver for the Maxim
 max98357a and some other driver specific fixes and enhancements.  I did
 apply a few patches that haven't been in -next just now before sending
 this, all fixes except for one simple device ID addition patch.

Ingenic JZ4740 I2S controller
Required properties:
- compatible : "ingenic,jz4740-i2s"
- reg : I2S registers location and length
- clocks : AIC and I2S PLL clock specifiers.
- clock-names: "aic" and "i2s"
- dmas: DMA controller phandle and DMA request line for I2S Tx and Rx channels
- dma-names: Must be "tx" and "rx"
Example:
i2s: i2s@10020000 {
compatible = "ingenic,jz4740-i2s";
reg = <0x10020000 0x94>;

Example:
max98357a {
compatible = "maxim,max98357a";
sdmode-gpios = <&qcom_pinmux 25 0>;
