mainboard/reef: add variant support to ASL code
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. The one thing not addressed in this CL
is the notion of a variant having the Chrome EC or not (along
with lid, etc). Future indirection can be provided when needed
to address that requirement.
