This series adds thermal nodes for UniPhier PXs2 and LD20 SoCs.
Changes in v1:
- separate from driver's patchset[1]
- add cooling-maps nodes on the device tree
- fix an interrupt trigger to set 'level-triggered' according to
hardware specification
- bring up threshold temperature for LD20 according to the spec sheet
- add cpuN labels for reference in cooling-device property on PXs2 dts

Add nodes of thermal monitor and thermal zone for UniPhier PXs2 SoC.
The thermal monitor is included in sysctrl.
Furthermore, add cpuN labels for reference in cooling-device property.
