Merge remote-tracking branches 'asoc/topic/wm8753' and 'asoc/topic/zte' into asoc-next

ZTE ZX296702 I2S controller
Required properties:
- compatible : Must be "zte,zx296702-i2s"
- compatible : Must be one of:
"zte,zx296718-i2s", "zte,zx296702-i2s"
"zte,zx296702-i2s"
- reg : Must contain I2S core's registers location and length
- clocks : Pairs of phandle and specifier referencing the controller's clocks.
- clock-names: "tx" for the clock to the I2S interface.
- clock-names: "wclk" for the wclk, "pclk" for the pclk to the I2S interface.
- dmas: Pairs of phandle and specifier for the DMA channel that is used by
the core. The core expects two dma channels for transmit.
- dma-names : Must be "tx" and "rx"
