A future change will set up gpio and pinmux platform device registration
in device-tree files, via board-dt.c. When board-dt.c calls into
harmony/seaboard_pinmux_init(), this will cause a duplicate registration
of those platform devices, which will cause kernel boot failure.
To solve this, modify harmony/seaboard_pinmux_init() so that they only
register the platform devices when actually running on Harmony/Seaboard;
when board-dt.c is in use, a different machine type is used.
This change is a temporary measure to ensure git bisectability. It will
be reverted when board-dt.c no longer calls harmony/seaboard_pinmux_init().
