meta-romulus: Add fan control yaml configs

1. The config follows Witherspoon's and remove water-cool/gpu/pcie
related configs.
2. Uses FanPwm interface instead of FanSpeed.
3. Removed zone_condition related config which is optional. Romulus is
always air cooled.
4. Updated to use groups for events.

Tested: Verified that fan control automatically adjust fan speeds based
        on temperatures.
