acpi: Add an __ACPI__ preprocessor symbol
The ASL compiler cannot handle C structures and the like so needs some sort of header guard around these. We already have an __ASSEMBLY__ #define but it seems best to create a new one for ACPI since the rules may be different. Add the check to a few files that ACPI always includes.
