arm64: Switch remaining uses of __ASSEMBLY__ to __ASSEMBLER__

Some arm64 files that were imported from other projects use the
__ASSEMBLY__ macro to test whether a header is included from a C or an
assembly file. This patch switches them to the coreboot standard
__ASSEMBLER__, which has the advantage of being a GCC builtin so that
the including file doesn't have to supply it explicitly.
