We need to add plat-s3c to the build to get the headers
that will go in here once moved from include/asm-arm so
we may as well put some useful common s3c code in here
to stop the errors generated form having nothing built.
The cpu setup is now passed the cpu idcode and the table
of supported cpus to s3c_init_cpu() to abstract the
cpu identification out of the initial io setup.
As well as moving the cpu initialisation code, we move the
map of the board specific items up to the calling code as
none of the map_io() functions actually do anything other
than pass this to iotable_init().
This patch does not rename any of the init functions that
will be common to s3c24xx and any other s3c architectures
as this can be done at a later date as it will touch all
the board support files which use functions such as
s3c24xx_init_clocks() and s3c24xx_init_uarts().
Note, the header arch/arm/plat-s3c24xx/include/plat/cpu.h
still has functions that are used by both the cpu and
board initialisation functions. This means that each board
has definitions specific to the cpu support included and
the vice-versa.

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.

Since 8d5796d2ec, we have allowed
PAGE_OFFSET to be configurable, so a constant virtual address
for MAX_DMA_ADDRESS is buggy. It should be defined in terms of
PAGE_OFFSET rather than a constant virtual address.

Let's provide an overridable default instead of having every machine
class define __virt_to_bus and __bus_to_virt to the same thing. What
most platforms are using is bus_addr == phys_addr so such is the default.
One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation. Also
added a comment about the special footbridge bus translation.
Let's also remove comments alluding to set_dma_addr which is not
(and should not) be commonly used.

Add a pin configuration callback for the s3c24xx SPI driver, as there are
several options depending on the channel and the chip in use.
This is needed as the controller may not have been setup by the initial
bootloader and the fact that the SPI controller gets reset over
suspend/resume into slave mode but the GPIO function registers do not.
