OMAPDSS: DSSCOMP: move device to omap plat to configure tiler1d slot

Different devices will have varying requirements on tiler resources. This
change moves the platform device registration for dsscomp to the omap
platform level so at device initialization time we can set the appropriate
Tiler1D slot size.
