Subject: [PATCH 13/15] ASoC: SND_S3C_DMA_LEGACY needs S3C24XX_DMA

From: Arnd Bergmann <arnd@...db.de>

SND_S3C_DMA_LEGACY can only be set on S3C24xx, which does not
(yet) support the dmaengine framework, so samsung_dma_get_ops()
fails to link if S3C24XX_DMA is disabled:

sound/built-in.o: In function `dma_hw_params':
:(.text+0x7f310): undefined reference to `s3c_dma_get_ops'
sound/built-in.o: In function `s3c_ac97_trigger':
:(.text+0x7f7f0): undefined reference to `s3c_dma_get_ops'
sound/built-in.o: In function `s3c_ac97_mic_trigger':
:(.text+0x7f884): undefined reference to `s3c_dma_get_ops'
sound/built-in.o: In function `s3c2412_i2s_trigger':
:(.text+0x80944): undefined reference to `s3c2410_dma_ctrl'

This makes sure S3C24XX_DMA is always enabled when we need
it, just like we do it for the same dependency in SND_S3C24XX_I2S,
which has the same problem. Selecting "S3C2410_DMA" as we did
before does not actually have the intended effect, since
that one is only used on the s3c2410 and s3c2442 SoCs of the
s3c24xx family, but not the others, so we can remove this
from Kconfig.
