I agree with you and I will look into more whether ARM_CPU_TOPOLOGY can
be removed safely since I can't make fully sure here and then update
those into the next version.

I will drop MT8173 wording because the driver also works for those
Mediatek SoCs not belonged to MT817x series.
In fact, the driver should also be extended and being more generic to
support more Mediatek SoCs in the future.
