>Description:
        The values of atf_arch and atf_machine do not match common sense.

        arch should refer to the CPU architecture whereas machine should
        refer to the machine type.  (I.e. there can be multiple machines
        with the same arch.)

        Unfortunately, for some weird historical reasons, this is not the
        case and the values of atf_arch and atf_machine are reversed.
        Kyua already does the right thing but we need to make ATF do this
        early so that we can correctly propagate the changes everywhere.
>How-To-Repeat:
        
>Fix:
        Reverse the definitions of atf_arch and atf_machine and adjust all
        existing test cases to reverse the definitions of these properties.
