To prepare for the removal of the global variable storing DSS private data, pass its pointer to the dss_runtime_{get,put}() functions. As this requires getting hold of the dss_device structure in the callers, we add a new dss_get_device() function to retrieve it. The function currently returns a pointer to the global data structure, and will later be updated to get the pointer from device driver data when the DSS private structure will be allocated dynamically.
