These two HW of wakeup don't follow MediaTek internal IPM rule, 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 compatible, treat specific ones without following IPM rule as revision 1.x, meanwhile reserve 3~10 for later revisions with following the IPM rule.
