OMAPDSS: modify get/find functions to go through the device chain
In the future will have arbitrarily long video pipeline chains, instead of the current two-entities-per-pipeline model. This patch changes the affected get/find style functions so that they properly go through the video pipeline chain, for example when getting the overlay manager connected to a given display.
