thermal: cooldev: update cpucore cooldev for multi cluster chip [1/1]

PD#SWPL-5366

Problem:
g12b cpucore cooling devices hotplug a little core and a big
when hot trippoint trigger, need to update cooling devices that
hotplug one core one hotstep for big core to little core.

Solution:
1.modify cpucore cooling for new solution.
2.modify hotplug core for can hotplug all big core.
3.ipa dts no cluster id, all cpucore is one cooling device
  dts have cluster id, one cluster is one cooling devices.

Verify:
test on g12b w400.
