For commonality, I duplicated what was already done for #define
MACHINE_START in this same file.  However, I'm not even entirely sure
that I'm going to keep this hunk around.  With some of the recent
changes to the arm-dt patches, a special DT machine id of 0xffffffff
is no longer needed.  This patch may get dropped in a future posting
of this series.
