Subject: [PATCH v2 1/1] arm64: dts: mediatek: mt8183: disable thermal zones without
 trips.

Thermal zones without trip point are not registered by thermal core.

tzts1 ~ tzts6 zones of mt8183 were intially introduced for test-purpose
only.

Disable the zones above and keep only cpu_thermal enabled.
