Toradex does provide device-tree overlays to enable certain evaluation
hardware. Keep the buses disabled by default to be enabled again with
overlays.

For customers including this device-tree this has also the advantage
that the hardware we want by default running does not automatically
enable signals on their end.

We idiomatically prefix i.MX arm DTS like 'ARM: dts: ...'  Please be
noted for the future patches.

Fixed prefix and applied the series.
