[PATCH v9,5/7] arm64: dts: mt8195: Add efuse node to mt8195

Add efuse node.
This will be required by the thermal driver to get the calibration data.

The SVS calibration efuse is for the SVS driver, not for the LVTS.
Moreover, you're not using it later when you add the LVTS nodes, so, please
drop this one.
