acpi: Move ACPI table support out of arch/x86 (2/5)
This change moves all ACPI table support in coreboot currently living
under arch/x86 into common code to make it architecture
independent. ACPI table generation is not really tied to any
architecture and hence it makes sense to move this to its own
directory.
In order to make it easier to review, this change is being split into
multiple CLs. This is change 2/5 which moves the contents of
arch/x86/include/arch/acpi*.h files into include/acpi/acpi*.h and
updates the arch header files to include acpi header files. These are
just temporary placeholders and will be removed later in the series.
