ARM: S5PC100: Kconfigs and Makefiles

S5PC100 is a new SoC with ARM coretex-A8 and numerous peripherals. This SoC is
successor of S3C64XX. S5PC100 has peripherals which are still similar to S3C
families so some drivers in "arch/arm/plat-s3c" can be shared. S5PC100 specific
drivers will be added in "arch/arm/plat-s5pcxx" or "arch/arm/mach-s5pc100"
