ODROID-N2: arm64: dts: meson: g12: Add minimal thermal zone

Add minimal thermal zone for two temperature sensor One is located close to the DDR and the other one is located close to the PLLs (between the CPU and GPU) Change-Id: Id1d710eeb3dd56b1fbd0048f2b8aa49ee444936b Acked-by: Martin Blumenstingl <[email protected]> Reviewed-by: Neil Armstrong <[email protected]> Reviewed-by: Amit Kucheria <[email protected]> Tested-by: Christian Hewitt <[email protected]> Tested-by: Kevin Hilman <[email protected]> Signed-off-by: Guillaume La Roque <[email protected]> Signed-off-by: Kevin Hilman <[email protected]>
