[ARM] S3C24A0: Initial architecture support files
Initial architecture support for the S3C24A0 ARCH_S3C24A0. We don't yet add an kconfig entry in the main arch/arm/Kconfig file as the series is not complete, so that is left until enough support is in to be useful. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
