Masahiro Yamada c14964fe8e ARC: define ASM_NL and __ALIGN(_STR) outside #ifdef __ASSEMBLY__ guard
[ Upstream commit 92e2921eea ]

ASM_NL is useful not only in *.S files but also in .c files for using
inline assembler in C code.

On ARC, however, ASM_NL is evaluated inconsistently. It is expanded to
a backquote (`) in *.S files, but a semicolon (;) in *.c files because
arch/arc/include/asm/linkage.h defines it inside #ifdef __ASSEMBLY__,
so the definition for C code falls back to the default value defined in
include/linux/linkage.h.

If ASM_NL is used in inline assembler in .c files, it will result in
wrong assembly code because a semicolon is not an instruction separator,
but the start of a comment for ARC.

Move ASM_NL (also __ALIGN and __ALIGN_STR) out of the #ifdef.

Fixes: 9df62f0544 ("arch: use ASM_NL instead of ';' for assembler new line character in the macro")
Fixes: 8d92e992a7 ("ARC: define __ALIGN_STR and __ALIGN symbols for ARC")
