Unfortunately the S3C24XX in master mode has a limited capacity of
generating the clock for the codec. If you define this only rates
that are really available will be enforced. But be careful, most
user level application just want the usual sampling frequencies (8,
11.025, 22.050, 44.1 kHz) and anyway resampling is a costly
operation for embedded systems. So if you aren't very lucky or your
hardware engineer wasn't very forward-looking it's better to leave
this undefined. If you do so an approximate value for the requested
sampling rate in the range -/+ 5% will be chosen. If this in not
possible an error will be returned.
