    armv4_5: fix output of command 'arm reg'
    
    Commit fc2abe63fd3c ("armv7m: use generic arm::core_mode") adds
    two special modes for ARMv6M and ARMv7M in struct arm_mode_data[].
    While these modes do not have any additional register to be dumped
    by command 'arm reg', the command still prints an header for these
    modes but not followed by any register.
    
    Detect the special modes for ARMv6M and ARMv7M and skip them to
    avoid printing the useless header.
