PM: fix compiler error of PPC dart_iommu
A dummy inline function of register_nosave_region_late was accidentally
removed by the recent PM patch that introduced suspend notifiers.
This elimination causes the following compiler error on PPC machines.
CC arch/powerpc/sysdev/dart_iommu.o
arch/powerpc/sysdev/dart_iommu.c: In function 'iommu_init_late_dart':
arch/powerpc/sysdev/dart_iommu.c:376: error: implicit declaration of function
'register_nosave_region_late'
make[1]: *** [arch/powerpc/sysdev/dart_iommu.o] Error 1
make: *** [arch/powerpc/sysdev] Error 2
This patch fixes the problem.
