Patch from Lucas Correia Villa Real

This patch modifies ocurrences of S3C2410_{VA,SZ} to S3C24XX_{VA,SZ},
as well as defining S3C2400 physical mappings on
include/asm-arm/arch-s3c2410/map.h.

This cleans up the naming of the virtual address macros, which are
fixed for all S3C24XX systems. This should clean up any confusion
about whether the virtual addresses are specific to the CPU or to
the arch.
