ARM: S5P6440: Move common memory map definitions for S5P

1. Moved common memory map definitions for S5P such as S5P_VA_XXX
   into plat-s5p/include/mach/map-s5p.h from mach-s5p6440/include/mach.
2. Removed unnecessary definitions in the map.h and irq.c
3. Removed the unnecessary support for unaligned UART address
4. Renamed S5P_VA_VICx definitions as VA_VICx
5. Moved the definitons of VIC_BASE to plat-s5p/include/plat/irqs.h
