Conditional registration is a problem for other subsystems which may unwittingly try to interact with host1x_context_device_bus_type in an uninitialised state on non-Tegra platforms. A look under /sys/bus on a typical system already reveals plenty of entries from enabled but otherwise irrelevant configs, so lets keep things simple and register our context bus unconditionally too.
