ASoC: s3c24xx-i2s: pass DMA channels as platform data
This is a minor cleanup to make the s3c2412-i2s and s3c24xx-i2s drivers independent of the mach/dma.h header file and to allow removing the dependency on the specific dmaengine driver in the next patch. As a side not, only the s3c24xx-i2s driver seems to still be used, while the definition of the s3c2412-i2s platform device was removed in commit 6d259a25b56d ("ARM: SAMSUNG: use static declaration when it is not used in other files") after it had never been referenced since its introduction in f0fba2ad1b6b ("ASoC: multi-component - ASoC Multi-Component Support"). Apparently it should have been used by mach-jive.c, but that never happened. My patch at this point leaves the current state unchanged, we can decide whether to fix or delete the jive driver and s3c2412-i2s another time.
