add nodes for the thermal controller and associated thermal zone using
CPU as the cooling device for each trip point. In addition, add a fixup
for thermal_calibration on nvmem should be 12 bytes as the minimal
requirement.

Any reason why this is not part of patch 8/16?

There's no strong reason wanting me to do that. patch 8 has contained a
lot of nodes and patch 16 is present just in v2. So, I felt it should be
a little bit easy that people reviews those patches if they are put into
separate patches. But, It's still fine to make them into one in the next
version.

Please add it to 8/16 as this is where you define the node in the first place.
