slimbus: core: add of_slim_device_get() helper
On SLIMBus controllers like Qcom NGD(non ported device), controller can request logical address once the remote side is powered, having a helper function like this to explicitly enumerate the bus is helpful. Also codec drivers which are taking to interface device would need such a helper too.
