Allwinner H3 features a thermal sensor like the one in A33, but has its
register re-arranged, the clock divider moved to CCU (originally the
clock divider is in ADC) and added a pair of bus clock and reset.

Update the binding document to cover H3.

Changes in v4:
- Add nvmem calibration data (not yet used by the driver)
Changes in v3:
- Clock name changes.
- Example node name changes.
- Add interupts (not yet used by the driver).
