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.

Since it seems to be a naming-convention to add -hog for gpio hogs do
this.

fix the naming of node-name vs label-name to the correct one, that is
the label was always correct.

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