As a final bit of preparation for converting to ARCH_MULTIPLATFORM,
change the interrupt handling for s3c24xx to use sparse IRQs.
Since the number of possible interrupts is already fixed and relatively
small per chip, just make it use all legacy interrupts preallocated
using the .nr_irqs field in the machine descriptor, rather than actually
allocating domains on the fly.

The SPI0 platform population function was taking a custom
gpio setup callback but the only user pass NULL as
argument so drop this argument.

The helpers to use SPI host 1 and 2 are unused in the kernel
and taking up space and maintenance hours. New systems should
use device tree and not this, so delete the code.

A lot of header files are only used internally now, so they can be moved
to mach-s3c, out of the visibility of drivers.

s3c24xx and s3c64xx have a lot in common, but are split across three
separate directories, which makes the interaction of the header files
more complicated than necessary.
Move all three directories into a new mach-s3c, with a minimal
set of changes to each file.
