MLK-16099-2: ASoc: fsl: length is not same for alloc and free memory

In fsl_hifi4_probe(), the length for dma_alloc_coherent() is
MSG_BUF_SIZE + INPUT_BUF_SIZE + OUTPUT_BUF_SIZE +
FIRMWARE_DATA_BUF_SIZE + SCRATCH_DATA_BUF_SIZE;

However, in fsl_hifi4_remove(), the length for dma_free_coherent()
is MSG_BUF_SIZE + INPUT_BUF_SIZE + OUTPUT_BUF_SIZE +
FIRMWARE_DATA_BUF_SIZE;

By keeping the same length between dma_alloc_coherent() and
dma_free_coherent() to fix this issue.
