The dss_mgr_ops operations implemented by the omapdrm side have to look
up the omap_crtc objects from global variables as they are only passed a
channel number. In order to remove global variables pass the
omap_drm_private pointer to the dss_mgr_ops. This requires storing a
pointer to the dss_device in the omap_dss_device structure to allow
looking up the omap_drm_private in the dss_mgr_*() functions.
