ASoC: S3C: I2Sv2: Reject immidiate register value

Towards generalizing CPU driver interface, do not accept direct field
values for the BCLK and RCLK.
The machine driver should simply request the FS-multiple and not provide
the value to be set in divide field of IISMOD.

[Confirmed by Jassi that no existing machine drivers are affected --
