Add zorder support on OMAP4, this feature allows deciding the visibility order of the overlays based on the zorder value provided as an overlay info parameter or a sysfs attribute of the overlay object. Use the overlay cap OMAP_DSS_OVL_CAP_ZORDER to determine whether zorder is supported for the overlay or not. Use dss feature FEAT_ALPHA_FREE_ZORDER if the caps are not available. Ensure that all overlays that are enabled and connected to the same manager have different zorders. Swapping zorders of 2 enabled overlays currently requires disabling one of the overlays.
