Subject: [PATCH v10 5/5] staging: vc04_services: vchiq_arm: Remove vchiq_register_child()

vchiq_register_child() is used to registered child devices as platform
devices. Now that the child devices are migrated to use the
vchiq_bus_type instead, they will be registered to that. Hence, drop
vchiq_register_child() as it is no more required.
