[PATCH] Use __ASSEMBLER__ instead of __ASSEMBLY__

Both, Clang and GCC define __ASSEMBLER__ automatically when
compiling .S files, so this macro is a much better fit for
fdt.h - programs that want to use it from .S files don't have
to manually #define __ASSEMBLY__ that way.
While we're at it, also change it in testdata.h, then we don't
have to define __ASSEMBLY__ in the Makefile / meson.build file
anymore.
