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:

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