I would like to move this modification to the patch of "Add BLS
component". Just like 'shadow register', even we first introduce it in
MT2701, we separate it in another independent patch because it may be
included in other Mediatek Soc. I prefer modification of this patch is
something which exist in MT8173 but is different in MT2701.
