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

Changed from v4:
1. support temperature threshold violation interrupts
2. completely switch codename to cv1800
3. style improvements
4. update e-mail address

Changed from v3:
1. style improvments
2. drop unnecessary dt parameters for simplicity

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