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
LD init/built-in.o
LD .tmp_vmlinux1
arch/powerpc/sysdev/built-in.o:(__ex_table+0x0):

arch/powerpc/sysdev/built-in.o:(__ex_table+0x6):
relocation truncated to fit: R_PPC64_ADDR16 against `.fixup'+c
arch/powerpc/sysdev/built-in.o:(__ex_table+0x8):

arch/powerpc/sysdev/built-in.o:(__ex_table+0xa):

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