ARM: exynos: move debug-macro.S to include/debug/
The move is necessary to support early debug output on exynos with multiplatform configurations. This implies also moving the plat/debug-macro.S file, but we are leaving the remaining users of that file in place, to avoid adding large numbers of extra configuration options to Kconfig.debug Signed-off-by: Arnd Bergmann <arnd@arndb.de>
