Generic sm8550 devicetree is split into a dtsi. Move it into its own DTB and preserve the boards as overlays. When not using overlays, 264 KB needed to store the sm8550-mtp.dtb and sm8550-qrd.dtb. When using overlays, 188 KB is needed to store sm8550.dtb, sm8550-mtp.dtbo, and sm8550-qrd.dtbo; where the overlays are ~36 KB. Also add the board-ids for these DTBs. This change is not intended to be merged, it breaks aliases and I doubt it boots correct. The intent here is to show how board-id could be used with a DTB and DTBO.
