    Replace __ASSEMBLY__ with compiler-builtin __ASSEMBLER__ · d5dfdeb6
    Julius Werner authored
    
    NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__.
    
    All common C compilers predefine a macro called __ASSEMBLER__ when
    preprocessing a .S file. There is no reason for TF-A to define it's own
    __ASSEMBLY__ macro for this purpose instead. To unify code with the
    export headers (which use __ASSEMBLER__ to avoid one extra dependency),
    let's deprecate __ASSEMBLY__ and switch the code base over to the
    predefined standard.
