[PATCH 1/2] ARM: S3C64XX: Clear DMA flags on channel request

[Mark Brown]

From: Charles Keepax <ckeepax at opensource.wolfsonmicro.com>

This patch clears the DMA flags when a DMA channel is requested. This is
necessary because otherwise the channel may inherit incompatible
settings from its last usage.
