This creates a direct dependency to dispc code, and we need to avoid this to make the compat code to work. Instead of the output drivers registering for dispc interrupts, we create new mgr-ops that are used to register a framedone handler. The code implementing the mgr-ops is responsible for calling the handler when DISPC FRAMEDONE interrupt happens. The compat layer is improved accordingly to do the call to the framedone handler.
