ACPICA: Merge all debug output macros into a single file, acoutput.
Moved the debug trace macros from acmacros.h into acoutput.h where they belong. Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
