OMAP display subsystem changes for 3.11 (part 1/2)

This is the first part of OMAP DSS changes for 3.11. This part contains fixes,
cleanups and reorganizations that are not directly related to the new DSS
device model that is added in part 2, although many of the reorganizations are
made to make the part 2 possible.

There should not be any functional changes visible to the user except the few
bug fixes.

The main new internal features:

- Display (dis)connect support, which allows us to explicitly (dis)connect a
  whole display pipeline

- Panel list, which allows us to operate without the specific DSS bus

- Combine omap_dss_output to omap_dss_device, so that we have one generic
  "entity" for display pipeline blocks
