The I2S block used for the audio codec in the A64 is very similar to what is used by the A10(sun4i) devices. However, its TX FIFO is located at a different address.
[vasilykh: - added fixed_wss and wss_value to A64 quirks, - changed compatible to 'allwinner,sun50i-a64-acodec-i2s, since A64 has 3 more I2S blocks that are not compatible with audio codec I2S]
