Actually I already duplicated those being used into scpsys-ext.h and
then replace the header file in patch 04/10

--- a/drivers/soc/mediatek/mtk-scpsys.c
+++ b/drivers/soc/mediatek/mtk-scpsys.c
@@ -11,7 +11,7 @@ 
-#include <linux/soc/mediatek/infracfg.h>
+#include "scpsys-ext.h"

so I remove the infracfg.h directly in this patch and add those new for
MT8183 in scpsys-ext.h
