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. Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Unfortunately the S3C24XX in master mode has a limited capacity of

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
