OMAPDSS: DISPC: Remove reduntant code for passing plane info

overlay id is being retrived from overlay that was not initialized during probe.
This will cause NULL pointer exception when accessing the ovl->id
directly when initializing the DISPC without initializing the
overlas/managers during probe.

overlays/managers are being initialized during probe with a call
to omapdss_compat_init(). This call is being made from dsscomp or omapfb
probe. if either of these components are not used by the rendering engine
then it will cause NULL pointer exception when accessing overlays frmo DISPC.
