ASoC: samsung: remove unused drivers

The s3c24xx SoC platform was completely removed, as were most of the
s3c64xx based board files, leaving only the DT based machines as well
as the MACH_WLF_CRAGG_6410 machine. All other board specific ASoC
driver can can now be recycled.

-  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.
