Lots of places in arch/arm were needlessly including linux/ptrace.h,
resumably because we used to pass a struct pt_regs to interrupt
handlers. Now that we don't, all these ptrace.h includes are
redundant.

On S3C24XX architecture, select CONFIG_NO_IOPORT
as we only have memory based IO.

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)

Remove the DMA code's channel printing at startup
as this is firstly a waste of console output on
initialsaion, and secondly is going to be obsolete
once the S3C2443 DMA code has been merged

Add arch/arm/mach-s3c2443 for support of the Samsung S3C2443 SoC
This patch adds the core CPU support, clock framework, times
and initial IRQ support, as well as adding the directory into
the build tree.

Allow the CPU code, and any board specific initialisation
code to change the allocation order of the DMA channels,
or stop a peripheral allocating any DMA at-all.
This is due to the scarce mapping of DMA channels on
some earlier S3C24XX cpus, where the selection changes
depending on the channel in use.

Don't save and restore cp register 15 since it is only a test register on S3C2410. This is probably a leftover from the PXA sleep.S from which this was derived.
Supersedes patch 4167.

The following patch and script moves the arch/arm/mach-s3c2410
directory into arch/arm/plat-s3c24xx for the generic core code
and inti arch/arm/mach-s3c{cpu} for the cpu/machine support files
Include directory include/asm-arm/plat-s3c24xx is added for the
core include files.
