CBS/CBM/CFS/CFM settings are controlled by BIT[3:4] of 0x60h

for example, for SND_SOC_DAIFMT_CBS_CFS: what we want is to clear both BIT[3:4].

aif_val = ~LM49453_AUDIO_PORT1_BASIC_CLK_MS | ~LM49453_AUDIO_PORT1_BASIC_SYNC_MS; actually set both bits.

Seems the my mail failed to reach alsa mailing list. I resend to LKML instead.
