PM: do not use saved_state from struct dev_pm_info on ARM
The saved_state member of 'struct dev_pm_info' that's going to be removed is used in arch/arm/common/locomo.c, arch/arm/common/sa1111.c and arch/arm/mach-sa1100/neponset.c. Change the code in there to use local variables for saving the state of devices during suspend. Signed-off-by: Rafael J.
