arm_adi_v5: abstract actions during ROM table parsing

Now all the actions (build command output) of command "dap info"
are decoupled from the ROM walk-through.
Pass the actions as a generic parameter to ROM walk-through code.
Put as private data every information that is only required by the
actions and not by the ROM walk-through.
