The audio controller on JZ47xx SoCs can transfer 20- and 24-bit samples in the FIFO, so allow those formats to be used with the I2S driver. Although the FIFO doesn't care about the in-memory sample format, we only support 4-byte format variants because the DMA controller on these SoCs cannot transfer in 3-byte multiples.
