ARM: S3C24XX: remove obsolete s3c2412 specific dma settings
From: Heiko Stuebner <heiko@...> Date: Sun, 21 Apr 2013 19:10:16 +0200
Commit-Message
The s3c2412 dma init contained code to handle dma-direction specific settings. As now all s3c2412-dma-channels are direction-independent this is not needed anymore. As the s3c2412 also was the only user of this, it can go away completely. Signed-off-by: Heiko Stuebner <heiko@...>
