The cs4265 uses 32 bit transport on the I2S bus. This patch enables native

Are you sure this is correct? The datasheet for the part only
says it supports up to 24-bit audio and I thought the defines
SNDRV_PCM_FMTBIT_S24_LE and U24 are expected to have 32-bits
in the slot whilst on the bus.
I will check this to make sure - leave it with me.
