OMAPDSS: SDI: Replace dssdev->manager with dssdev->output->manager references
With addition of output entities, a device connects to an output, and an output connects to overlay manager. Replace the dssdev->manager references with dssdev->output->manager to access the manager correctly. When enabling the SDI output, check whether the output entity connected to display is not NULL.
