This patch adds dma maxburst size initialization.
The maxburst should be set by MODE_CFGn.DMA_TYPE,
because the pl330 dma driver supports burst mode.

Config operation is separated from request operation in DMA common operation.
Because spi driver can change the DMA config for every transfer.
So this patch is using the separated DMA config operation.

This patch adds to support the DMA PL330 driver that uses
DMA generic API. Samsung sound driver uses DMA generic API
if architecture supports it. Otherwise, use samsung specific
S3C-PL330 API driver to transfer PCM data.

This patch modifies to merge the dma control code. Original
s3c64xx spi driver has each dma control code for rx and tx
channel. This patch merges these dma control codes into one.
With this patch, a dma setup function and callback function
handle for both rx and tx channel.
