dt-bindings: thermal: loongson,ls2k-thermal: Fix incorrect compatible definition
[ Upstream commit c8c4353685778e75e186103411e9d01a4a3f2b90 ]
The temperature output register of the Loongson-2K2000 is defined in the
chip configuration domain, which is different from the Loongson-2K1000,
so it can't be fallbacked.
We need to use two groups of registers to describe it: the first group
is the high and low temperature threshold setting register; the second
group is the temperature output register.
It is true that this fix will cause ABI corruption, but it is necessary
otherwise the Loongson-2K2000 temperature sensor will not work properly.
