bus: ti-sysc: Fix sysc_unprepare() when no clocks have been allocated

[ Upstream commit aaa29bb01cc4bf5a87dbdb219efba3b09f259d8e ]

If we return early before ddata->clocks have been allocated we will get a
NULL pointer dereference in sysc_unprepare(). Let's fix this by returning
early when no clocks are allocated.
