ARM: s3c64xx: Add support for DMA using generic amba-pl08x driver
This patch adds all required platform-specific data and initialization
code to support the generic amba-pl08x driver on S3C64xx SoCs.
Also some compatibility definitions are added to make the transition
from legacy API to DMA engine easier. The biggest hack here is passing
const char * pointers through DMA resource, casted to unsigned long,
but this is how Samsung DMA wrappers (used to support both s3c-dma and
DMA engine in drivers) are designed.

ARM: SAMSUNG: Make dma request compatible to generic dma bindings.
This patch make the dma dev request operation compatible for both
DT and non-DT cases. It takes the all the arguments required for
dma_request_slave_channel and dma_request_channel. If the driver
is initiated via DT or non-DT the corresponding call will be made.

ARM: SAMSUNG: Add config() function in DMA common operations
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().

dmaengine/dma_slave: introduce inline wrappers
Add inline wrappers for device_prep_slave_sg() and device_prep_dma_cyclic()
interfaces to hide new parameter from current users of affected interfaces.
Convert current users to use new wrappers instead of direct calls.

ARM: SAMSUNG: Add device tree support for pl330 dma engine wrappers
A new dma request id 'DMACH_DT_PROP' is introduced for client drivers
requesting a dma channel. This request indicates that a device tree
node property represting the dma channel is available in
'struct samsung_dma_info'. The dma channel request wrapper uses the
node property value as the value for the filter parameter.

DMA: PL330: move filter function into driver
The dma channel selection filter function is moved from plat-samsung
into the pl330 driver. In additon to that, a check is added in the
filter function to ensure that the channel on which the filter has
been invoked is pl330 channel instance (and avoid any incorrect
access of chan->private in a system with multiple types of DMA
drivers).

These files didn't exist at the time of the module.h split, and
so were not fixed by the commits on that baseline. Since they use

ARM: SAMSUNG: Add common DMA operations
This patch adds common DMA operations which are used for Samsung DMA
drivers. Currently there are two types of DMA driver for Samsung SoCs.
The one is S3C-DMA for S3C SoCs and the other is PL330-DMA for S5P SoCs.
This patch provides funcion pointers for common DMA operations to DMA
client driver like SPI and Audio. It makes DMA client drivers support
multi-platform.
In addition, this common DMA operations implement the shared actions
that are needed for DMA client driver. For example shared actions are
filter() function for dma_request_channel() and parameter passing for
device_prep_slave_sg().
