[RFC PATCH 2/5] ARM: s3c24xx: Reference cpu_architecture as a global variable

[dave.martin@linaro.org (Dave Martin)]

This patch is needed for compatibility with the change of
cpu_architecture from a function to a global variable.

Since cpu_architecture is ARM-specific, also add an explicit
include for <asm/system.h> rather than relying on this being
included as a side-effect.
