rs6000: Change bitwise xor to an equality operator [PR106907]

Browse source 
PR106907 has a few warnings spotted from cppcheck. These warnings
are related to the need of precedence clarification. Instead of using xor,
it has been changed to equality check, which achieves the same result.
Additionally, comment indentation has been fixed.
