Parentheses not needed. I am also curious if ARM_CPU_TOPOLOGY can actually be set when neither ARM nor ARM64 is. I suspect not, and then the above can be simplified to just:
depends on ARM || ARM64

If this driver actually support all Mediatek SoCs, the menu entry itself should be updated to drop "MT8173".
