Now that the hooks are optional, we can eliminate all the stubs.

This would make it difficult to manage connecting the display entities in the future, as the code cannot just search for a suitable overlay manager. We cannot fix this the sane way, which would be to create crtcs for each overlay manager, because we need an overlay for each crtc. With limited number of overlays, that's not possible. So the solution for now is to detach the overlay manager from the crtc. crtcs are still created on demand at init time, but all overlay managers are always initialized by the omapdss. This way we can create and connect whole display pipelines from the overlay manager to the display, regardless of which crtcs omapdrm would create.

After the panel has been probed, it's ready and can be configured and later enabled. This model is not enough with more complex display pipelines, where we may have, for example, two panels, of which only one can be used at a time, connected to the same video output. To support that kind of scenarios, we need to add new step to the initialization: connect. This patch adds support for connecting and disconnecting panels. After probe, but before connect, no panel ops should be called. When the connect is called, a proper video pipeline is established, and the panel is ready for use. If some part in the video pipeline is already connected (by some other panel), the connect call fails. One key difference with the old style setup is that connect() handles also connecting to the overlay manager. This means that the omapfb (or omapdrm) no longer needs to figure out which overlay manager to use, but it can just call connect() on the panel, and the proper overlay manager is connected by omapdss. This also allows us to add back the support for dynamic switching between two exclusive panels. However, the current panel device model is not changed to support this, as the new device model is implemented in the following patches and the old model will be removed. The new device model supports dynamic switching.

Then we have omap_dss_output, which represents DSS's output encoder. In the future with new display device model, we construct a video pipeline from the display blocks. To accomplish this, all the blocks need to be presented by the same entity. Thus, this patch combines omap_dss_output into omap_dss_device. Some of the fields in omap_dss_output are already found in omap_dss_device, but some are not. This means we'll have DSS output specific fields in omap_dss_device, which is not very nice. However, it is easier to just keep those output specific fields there for now, and after transition to new display device model is made, they can be cleaned up easier than could be done now.
