PS1, Line 9: This patch fixes AP hanging issue caused by CPU input gating. The
           : feature should be disabled by default, so we disable it.
> If it's by default disabled then we don't need to anything, isn't it? 😊 […]

1. CPU input gating (IG), please refer to https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=8778108

2. It is an experimental feature (but unfortunately default
enabled) and would lead to crash on MT8188.
