powerpc/sstep: Use bitwise instead of arithmetic operator for flags 

Fix the following coccinelle warnings:
./arch/powerpc/lib/sstep.c:1090:20-21: WARNING: sum of probable
bitmasks, consider |
./arch/powerpc/lib/sstep.c:1115:20-21: WARNING: sum of probable
bitmasks, consider |
./arch/powerpc/lib/sstep.c:1134:20-21: WARNING: sum of probable
bitmasks, consider |
