This series implements driver for Sophgo cv180x/sg200x on-chip thermal
sensor and adds thermal zones for CV1800B SoCs.

Changed from v2:
1. style and code improvements
2. use human-readable value for sensor parameters

Changed from v1:
1. style and code improvements
2. make sample parameters configurable
3. generalize document temperature calculating formula
