hppa: Don't use '%' operator in base14_operand

Division is slow on hppa and mode sizes are powers of 2.  So, we
can use '&' operator to check displacement alignment.

gcc/ChangeLog:

        * config/pa/predicates.md (base14_operand): Use '&' operator
        instead of '%' to check displacement alignment.
