In previous version of the machine driver I used a different CPU
component than acp-i2s-sp. For that one, I couldn't get it to have
sound unless I specifically requested S32 LE format.

I removed S32_LE from the CODEC to test if it works and it
seems it does work with acp-is2-sp. Format S16_LE is chosen by
both components and sound can be heard. I guess this patch is
not really needed.
