Subject: [PATCH v2 2/2] arm64: dts: mediatek: mt8188: Change efuse fallback compatible to mt8186

The efuse block in the MT8188 contains the GPU speed bin cell, and like
the MT8186 one, has the same conversion scheme to work with the GPU OPP
binding. This was reflected in a corresponding change to the efuse DT
binding.

Change the fallback compatible of the MT8188's efuse block from the
generic one to the MT8186 one. This also makes GPU DVFS work properly.

Fixes: d39aacd1021a ("arm64: dts: mediatek: mt8188: add lvts definitions")
Fixes: 50e7592cb696 ("arm64: dts: mediatek: mt8188: Add GPU speed bin NVMEM cells")
