arm64: dts: mediatek: mt8395-genio-1200-evk: Describe CPU supplies

The Genio 1200 EVK board has the big and little CPU clusters fed by the
same regulators as MT8195-Cherry boards, so describe them in the same
way as commit 17b33dd9e4a3 ("arm64: dts: mediatek: cherry: Describe CPU
supplies").

This prevents the system from hanging during boot in the case that the
cpufreq-mediatek-hw driver tries to probe before the drivers for the
regulators have probed (which happens when using the current defconfig).

Fixes: f2b543a191b6 ("arm64: dts: mediatek: add device-tree for Genio 1200 EVK board")
