Subject: [PATCH v4 5/6] ARM: sun8i: h3: add support for the thermal sensor in H3

As we have gained the support for the thermal sensor in H3, we can now
add its device nodes to the device tree.

Add them to the H3 device tree.

The calibration data of the thermal sensor is still not added, as
it's currently not used, and the SID node is not added yet.

The H5 thermal sensor has some differences, and will be added furtherly.

Signed-off-by: Icenowy Zheng <icenowy@...c.io>
Reviewed-by: Chen-Yu Tsai <wens@...e.org>
---
Changes in v4:
- Mention calibration data in commit message.
Changes in v3:
- Clock name changes.
- Splited out thermal zone addition.
