v7:
- don't allocate twice the memory for the RTAS call
- add "-machine pseries" in rtas-test

As a sanity check you could return an error if you're unable to
resolve the machine as an sPAPR here. Since that should only happen
on a broken testcase, it can be done as a later enhancement, though.

This might be slightly more robust if the args were put into an actual
rtas args buffer (with the token not populated), rather than separate
args and rets array. Again, that can be a later improvement though.
