ASoC: jz4740-i2s: Support S20_LE and S24_LE sample formats
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.
