According to commit c4806174c5
(ARM: S3C2412: DMA: Remove I2S FIFO address) the S3C DMA API does not
make use of hw_addr.to/from declared for some of the channels in
mach-s3c24XX/dma.c
Grepping through the kernel also did non reveal any new users of
these properties since the mentioned commit.

This patch removes the samsung specific enum type 's3c2410_dmasrc'
and uses 'dma_data_direction' instead.

The S3C DMA API doesn't make use of hw_addr.to/from and also
the FIFO addresses are provided from the I2S drivers. So these
fields are redundant.
This patch removes the hw_addr.to/from fields for I2S and the
inclusion of header, paving way for the header to be moved closer
to the I2S controller drivers.

dma-plat.h is the last file left in plat-s3c64xx, but to remove it we
must also change the use of dma-plat.h by the core code and the s3c24xx
implementation.
Rename the s3c24xx dma-plat.h in the common plat-samsung directory as it
may be used for other ports. Move the specific dma bits into the
mach-s3c64xx directory and update the build as needed.

The <mach/dma.h> is for the driver API for the DMA system and should
not have anything relying on the CPU specific registers.
Remove the registers to <plat/dma-regs.h> for the code that really
needs to know about them.

When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
so there's no point in publishing the prototypes via asm/dma.h, nor
including the machine dependent parts of that API.
This allows us to remove a lot of mach/dma.h files which don't contain
any useful code. Unfortunately though, some platforms put their own
private non-ISA definitions into mach/dma.h, so we leave these behind
and fix the appropriate #include statments.

First move of items out of include/asm-arm/plat-s3c* to their
new homes under arch/arm/plat-s3c/include/plat and
arch/arm/plat-s3c24xx/include/plat directories.
Note, we have to create a dummy arch/arm/plat-s3c/Makefile to
allow us to add arch/arm/plat-s3c/include/plat to the path.

The current S3C24XX DMA code does not allow for an peripheral
that has one channel for RX and another for TX.
This patch adds a per-cpu dma operation to select the transmit
or receive channel, and adds support to the S3C2412 for the
seperate DMA channels for TX and RX.

Move register and other definitions out of the
include/asm-arm/arch-s3c2410 into the the arch
directories of include/asm-arm/plat-s3c24xx and
include/asm-arm/plat-s3c.
This move is in preperation of the merging of
s3c2400 and s3c6400.

This patch gets the DMA system for the S3C24XX
ready for the S3C2443, which requires 6 dma channels
at a different stride, and different base IRQ.
The DMA system is now initialised from the same
drivers which apply the DMA mappings, as well
as removing the DMA sysdev intialisation out of
the main init code (which is now being called
from a sysdev probe, so cannot add a new sysdev)
