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.

This patch adds config() that configures DMA transmit option.
This function was originally included in request().
But, Some DMA client driver requires to change the configuration after
request().
So, This patch picks up it from request().

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 patchset adds support DMA generic APIs for Samsung DMA.
The changes from V4 are following:
- Change DMA cyclic capability operation on '04 patch'
- Remove cyclic_task
- Initialize 'cyclic' variable on channel request.
- Change pl330 data structure on '02, 07, 08, 09, 10
This patch updates following 3 items.
1. Removes unneccessary code.
2. Add AMBA, PL330 configuration
3. Change the meaning of 'peri_id' variable
from PL330 event number to specific dma id by user.

This patch adds DMA_CYCLIC capability that is used for audio driver.
DMA driver activated with it reuses the dma requests that were submitted
through tx_submit().
