These two HW of wakeup don't follow MediaTek internal IPM rule, and both use a specific way, like as early revision of mt8173. Due to the index 2 already used by many DTS, it's better to keep it unchanged for backward compatibility, treat specific ones without following IPM rule as revision 1.x, meanwhile reserve 3~99 for later revision that following the IPM rule.
