OMAPDSS: DISPC: Configure overlay-like parameters in dispc_wb_setup
Create struct omap_dss_writeback_info, this is similar to omap_overlay_info, the major difference is that there is no parameter which describes the input size to writeback, this is because this is always fixed, and decided by the connected overlay or overlay manager. One more difference is that screen_width is renamed to buf_width, to give the value of stride the writeback buffer has. Call dispc_ovl_setup_common() through dispc_wb_setup() to configure overlay-like parameters. The parameters in dispc_ovl_setup_common() which do not hold for writeback are filled passed as zeroes or false, the code takes care of not configuring them as they won't possess the needed overlay caps.
