Subject: [PATCH v2 0/3] hwmon: (amc6821) Add Cooling device support

Add support for using the AMC6821 as a cooling device. The AMC6821
registers with the thermal framework only if the `cooling-levels`
property is present in the fan device tree child node. Existing behavior
is unchanged, so the AMC6821 can still be used without the thermal
framework (hwmon only).

v2:
- Remove devm_action on release and call of_node_put() manually
- Change of_pwm_polarity to store resulting pwm polarity on driver private data
v1:
- https://lore.kernel.org/lkml/20250530-b4-v1-amc6821-cooling-device-support-b4-v1-0-7bb98496c969@toradex.com/
