There are certain board-specific options for reef variants. The big one is the DPTF settings. Rearrange the ASL files such that dsdt.asl is the main landing area. The ACPI options for Chrome EC are contained in the variant/ec.h header so the actual code #includes can just reside in dstd.asl. Since most of the mainboard specific peripherals are auto generated by the acpigen from devicetree there's no real separate need for mainboard.asl.
