acpi: Pass -D__ASSEMBLY__ when compiling ASL files

Browse source 
ASL files may include various U-Boot header files, but IASL compiler
does not understand any C language embedded in these header files.
To reuse those header files for ASL compiling, use __ASSEMBLY__ in
the header files to exclude everything that is not liked by IASL.
