arm: Fix the "c" constraint

The existing definition using register class CC_REG does not
work because CC_REGNUM does not support normal modes, and so
fails to match register_operand.  Use a non-register constraint
and the cc_register predicate instead.

        * config/arm/constraints.md (c): Use cc_register predicate.
