thermal/core: Introduce non-OF thermal_cooling_device_register()

Browse Source 
Split the cooling device registration API into OF and non-OF variants.

Introduce thermal_cooling_device_register() for non-device-tree users
and rework thermal_of_cooling_device_register() to use the new
alloc/add split.

This removes the need for the internal __thermal_cooling_device_register()
helper and makes the separation between OF and non-OF users explicit.
