arm64: dts: mediatek: mt8183: Refactor thermal zones

Browse Source 
The thermal zones in MT8183 had cryptic names and all of them, apart
from the cpu-thermal zone, had no thermal trips, hence those were not
probed at all.

Refactor the tzts1..5 and tztsABB thermal zones to add the correct
thermal trips and give them a meaningful name, corresponding to the
actually monitored thermal zone.
While at it, also rename the thermal sensor node to "thermal-sensor".

Now the thermal zones are probing and their temperatures can be read.

Fixes: b325ce3978 ("arm64: dts: mt8183: add thermal zone node")
