Hi everyone,

This is the second version of the I2S support for the controller found
in the Allwinner A10 and later SoCs.

Playback has been tested with an UDA1380 on an A20-Olinuxino. Capture
is not implemented yet, but will come eventually.

Let me know what you think,
Maxime

Changes from v1:
  - Fixed bogus indentation and spurious whitespaces / newlines
  - Moved the device initialisation in the probe to the startup function
  - Disabled the device in shutdown
  - Removed function to get wss and sr to inline them in hw_params
  - Changed the way to access the divider array
  - Checked clk_set_rate return code
  - Fixed condition for invalid bclk and mclk dividers
  - Added sound-dai-cells to the bindings documentation required properties

Tested-by: Chen-Yu Tsai <redacted>

on a BPI-M1+ with a TI PCM5122-based PiFi DAC+ v2.0, a Raspberry Pi B+
compatible DAC shield.

I kept getting low but audible pops though. Not sure if it's the
ad-hoc setup or some other factor.
