target-arm/helper.c: Allow const opaques in arm CP
Allow for defining const opaque data in ARM CP register definitions by
setting .opaque = foo. If non null opaque is passed into
define_one_arm_cp_reg_with_opaque then that opaque will take
precedence, otherwise if null opaque is passed, the original opaque
data will be used.
