thermal/core: Add devm_thermal_cooling_device_register()

thermal/core: Add devm_thermal_cooling_device_register()

Introduce a device-managed variant of the non-OF cooling device
registration API.

This complements devm_thermal_of_cooling_device_register() and allows
non-device-tree users to register cooling devices with automatic
cleanup tied to the device lifecycle.

The helper relies on devm_add_action_or_reset() to release the cooling
device via thermal_cooling_device_release() on driver detach or probe
failure.

This keeps the API consistent across OF and non-OF users and avoids
manual cleanup in error paths.
