[PATCH] ARM: 2644/1: Adds S3C2400 support to uncompress.h 

Patch from Lucas Correia Villa Real

The S3C2400 doesn't have a cpuid information stored anywhere. This patch adds
support to the S3C2400 at include/asm-arm/arch-s3c2400/uncompress.h by
initializing the cpuid variable to the S3C2410, as they share the same
routine. The GSTATUS1 pin is then used only if not compiling for the S3C2400.
