slimbus: qcom-ngd-ctrl: Fix up platform_driver registration

Browse source

Device drivers should not invoke platform_driver_register()/unregister()
in their probe and remove paths. They should further not rely on
platform_driver_unregister() as their only means of "deleting" their
child devices.

Introduce a helper to unregister the child device and move the
platform_driver_register()/unregister() to module_init()/exit().
