The existing norm is that omap_devices are never destroyed.  The same is
true for the way we handle platform_devices that are not omap_devices.
That being said, it doesn't answer the question of how we would destroy
them if we wanted to, and that does indeed deserve some discussion.

However, I think your confusion is more about the separation between
device code and driver code.

It is the responsibility of device init code (arch/arm/*omap*) to create
and register devices with the system.  This is where platform_devices
and omap_devices are handled currently.

The drivers then register themselves (as platform_drivers) with the
driver core, and the driver core hooks them together.

The goal we're working towards is that the drivers be generic, and
should not know anything about device-specific registration.
