[ Upstream commit 3969341813eb56d2dfc39bb64229359a6ae3c195 ]
According to RM, on auto mode: For codec AK4458 and AK4497, the lowest ratio of MLCK/FS is 256 if sample rate is 8kHz-48kHz, For codec AK5558, the lowest ratio of MLCK/FS is 512 if sample rate is 8kHz-48kHz.
With these setting the sound quality for 8kHz-48kHz can be improved.
