ARM: 7246/1: S5P64X0: introduce arch/arm/mach-s5p64x0/common.[ch]
This patch introduces common.[ch] which are used only in the arch/arm/mach-s5p64x0/ directory. The common.c file merges the cpu.c, init.c and irq-eint.c files which are used commonly on S5P64X0 SoCs and the common.h local header file replaces with plat/s5p6440.h and plat/s5p6450.h files.
