marlin: audio: keep QUAT_MI2S bit format at 24

Since QUAT_MI2S_TX and QUAT_MI2S_RX share the same cpu_dai
at kernel driver, the rx/tx path will open fail if the
bit format of QUAT_MI2S_TX and QUAT_MI2S_RX are different.

To fix rx/tx path open fail due to format different, enfore
QUAT_MI2S bit format always to be 24.
