Add the DAI blocks to the device tree. I2S0 and I2S1 are for
connecting to an external codec.

Same remark than for the spdif, please add a soc-specific compatible.

Is that really necessary?..for example on the a20 the functionality of
the i2s is the same as the a10 so it is down as
"allwinner,sun4i-a10-i2s", likewise here it's the same as the changes
required for the H3. I was planning on using the compatible
"allwinner,sun50i-a64-i2s" for the audio codec as there are some
quirks that need to be addressed.

Thanks,
CK

Thanks!
Maxime
