ARM: OMAP2+: display: Create omapdrm device inside omap_display_init
Move omapdrm device creation inside the omap_display_init so that we can correctly create the device based on the presence of omapdss within the platform. For example, on a kernel image supporting multiple platforms, omap_init_drm will create a omapdrm platform device on a AM33xx platform even though it doesn't have a DSS block. Originally worked on by Andy Gross.
