This device receives audio over an I2S DAI and as such should have endianness applied. A fixup is also required to use the width directly rather than relying on the format in hw_params, now both little and big endian would be supported. It is worth noting this changes the behaviour of S24_LE to use a word length of 24 rather than 32. This would appear to be a correction since the fact S24_LE is stored as 32 bits should not be presented over the bus.
