ANDROID: of: property: Enable of_devlink by default

The of_devlink feature creates device links between devices based on
the common device tree bindings listed in their device node. This
allows improved probe ordering and also makes sure the sync_state()
calls to the device drivers come only after all the consumers of a
device have probed successfully.

Enable this by default on Android since this is required to ease
modularization efforts for GKI.
