From: Sean Wang <sean.wang@mediatek.com>

MT2701/MT7623 is an 32-bit ARMv7 based quad-core (4 * Cortex-A7) with
single cluster and this hardware is also compatible with the existing
driver through enabling CPU frequency feature with operating-points-v2
bindings.

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
 	depends on !CPU_THERMAL || THERMAL

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