With the introduction of output entities, managers will now connect to outputs.
Use the helper op for managers named get_device. This will abstract away the
information on how to get the device from an overlay manager.
Using the helper function will reduce the number of pointer dereferences a user
of OMAPDSS needs to do and reduce risk of a NULL dereference.
Almost all the uses here seem to be getting the dssdev from an overlay.
Would it make sense to implement get_device for an ovl? That would
reduce all the ovl->manager ? ovl->manager->get_device(ovl->manager) :
NULL; code to ovl->get_device(ovl).
That make sense.
We would still need mgr->get_device() though, as in some places, dss and
drm try to get the display from the manager.
