powerpc/srio: Fix the relocation errors when building with 64bit

For the file "arch/powerpc/sysdev/fsl_rio.c", there will be some relocation
errors while using the corenet64_smp_defconfig:

WARNING: modpost: Found 6 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
  GEN     .version
  CHK     include/generated/compile.h
  UPD     include/generated/compile.h
  CC      init/version.o

arch/powerpc/sysdev/built-in.o:(__ex_table+0xa):
	relocation truncated to fit: R_PPC64_ADDR16 against `.fixup'+18

Rewrote the corresponding code with the support of 64bit building.
