[ARM PATCH] 1243/1: Add support for Ceiva Photoframe, part2: machine specifics (fixed)

Adds machine specific support for Ceiva Photoframe. Affects:
arch/arm/mach-clps711x/Makefile 
arch/arm/mach-clps711x/ceiva.c (new)
include/asm-arm/arch-clps711x/hardware.h
include/asm-arm/arch-clps711x/memory.h

Differences from 1st patch:
Removed redundant static I/O mapping for flash from hardware.h
Reverted to original CONFIG_DISCONTIGMEM enabling in memory.h
Added PHYS_TO_NID definition, when DISCONTIG undefined in memory.h
