The usb micro-b port on p3450 is capable of otg and doesn't need
hardcoded to peripheral. No other supported tegra device is set up like
this, so align for consistency.

Friendly reminder about this patch.
Re-reminder about this patch.
Sorry for missing this earlier. We're in the middle of the merge window
now, so I can't apply this to a tree that feeds into linux-next, but I
will pick it up once the merge window closes.

Thanks,
Thierry
