[ARM] 4963/1: S3C2410 - add basic machine support for the TCT Hammer

Add the TinCanTools Hammer board to list of supported machines in the
arch/arm/mach-s3c2410 directory, as well as a default config entry. the
mach-tct_hammer.c file initializes basic i/o, clocks, irqs, as well as
the mtd flash layout if enabled in the kernel configuration.
