In a multiplatform kernel, each initcall is run regardless of the platform it is meant for, so it must not attempt to access SoC-specific registers. This adds 'if (soc_is_s3c64xx)' to all initcalls that are specific to the s3c64xx platform, to prevent them from breaking other platforms once we can build them into a combined kernel.
